You will get efficient and thoughtful service from NB.
Application Tape/Transfer Tape - Transfer tape or application tape, also known as “pre-mask”, is a necessity for sign-making and digital graphics. Transfer tape is so named because it transfers cut vinyl and graphics from the release liner to the substrate. High quick tack and good shear strength make this the best choice for more demanding bonding/joining applications, especially for textured, rough surfaces. Used for core starting, and splicing of papers, films, metals, and other webs.
Barricade Tape - Brightly colored tape (often incorporating a two-tone pattern of alternating yellow-black or red-white stripes or the words “Caution” or “Danger” in prominent lettering) that is used to warn of an area or situation containing a possible hazard. Underground detectable tape is used for accurately locating and preventing damage to valuable underground utility installations.
Carton Sealing Tape (Acrylic Water-Based Adhesive) - Water-based adhesives service a huge variety of industries because of their ability to bind to a wide range of substrates. They also remain stable in high levels of humidity and across a wide temperature range and form extremely strong and durable bonds. Along with their flexibility and economic practicality, water-based adhesives offer excellent adhesive qualities and service a wide range of temperatures and are more resistant to moisture.
Carton Sealing Tape (Acrylic Solvent-Based Adhesive) - Solvent acrylic adhesives are formulated to offer extraordinary chemical resistance, making them well-suited for use in environments where such exposure is a possibility. In addition, many solvent adhesives can withstand a range of temperature extremes. As with chemical resistance, the ability of solvent acrylics to function at high and low temperatures enables their use across a wider range of locations and conditions than some competing technologies. Finally, when longevity and durability define success or failure, solvent acrylic adhesives are often the best option.
Carton Sealing Tape (Hot Melt Rubber-Based Adhesive) - Recommended for an initial quick-stick. Hot melt adhesives have a quick set speed and are applicable in a wide range of temperatures and industries. They rely on cooling to set vs evaporation. Excellent adhesion to challenging substrates, especially to low surface energy plastic substrates such as polyethylene and other polyolefins. Excellent resistance to humidity and water. These adhesives can also be applied to moist substrates and even to slightly contaminated substrates. Specific grades exhibit excellent adhesion even under extreme cold conditions (down to -18°C).
Carton Sealing Tape (Natural Rubber-Based Adhesive) - Recommended for recycled cartons and cold-temperature applications. In general, natural rubber properties offer many advantages for adhesive tape applications. The first of these is its outstanding peel adhesion or “grab” – not only on polar surfaces but also on substrates with low surface tension. Furthermore, adhesive tape with natural rubber adhesion can be removed easily and does not leave any trace. Finally, there is the high tack, i.e. stickiness, of the adhesive: the adhesive tape glues with minimal pressure and minimal contact time.
Cloth Tape - Very good for bonding to rough surfaces and can be removed quickly and cleanly after use. The cloth carrier resists tearing yet is hand tearable. Cloth tape is suited for long-term interior and exterior applications. It is extremely resistant, waterproof, offers immense adhesive performance, and can be used to bundle or package items as well as for handicrafts. Tapes are available in various colors and can be written on.
Double Coated Tissue Tape - Exhibits a strong direct tack and continuous adhesive strength, as well as dynamic shear strength on most surfaces. No plasticizer migration on most surfaces and excellent corrugators’ splicing tape. Used in manufacturing for continuous web processes when a visual splice is needed. Good temperature, UV, and aging resistance.
Double-Sided Paper Tape - Good quick stick, great adhesive strength, and bonds to most surfaces. Used in the printing industry, textile manufacturing (twisting/spinning process), steel rule die-makers/die-cutters (make-ready), and carpet installation. For bonding, mounting, holding, joining, core start-ups, and splicing applications.
Duct Tape - Duct tape will conform well to irregular surfaces, and will not twist or curl during application. Excellent water and abrasion resistance. It is hand-tearable and tears evenly. Used as a quality waterproof packaging tape for export shipments. Used for splicing, vinyl repair, protecting, bundling, color coding, and ductwork sealing and seaming.
Electrical Tape - For wire and cable insulation, bundling, and primary splice insulation at no more than 600V. Most electrical tapes are non-flame retardant but are also available in flame retardant, cold resistant, and all-weather versions. Color options are available for cable coding and quick identification of electrical phases, circuits, feeders, and branches.
Filament Strapping Tape - Filament tape or strapping tape is used for medium and heavy-duty strapping, bundling, and palletizing applications. It contains a polypropylene or polyester film backing with fiberglass filaments embedded, giving the tape a high tensile strength.
Film Tape - Good adhesion for surface protection applications. The tough polyethylene backing offers good abrasion and tear resistance. UV and solvent-resistant. Long-term aging stability without yellowing. The tape will not crack or craze after extended exposure.
Flagging Tape - Non-adhesive plastic marking ribbon used for surveying, mapping, tagging, roping off areas, or any other marking applications.
Flatback Paper Tape - The flat surface (vs. creped paper) results in high-quality printing. Easy unwind characteristic for high-speed printing. For flexographic printing, color coding, identification (write-on surface). This tape exhibits high face-to-face bond strength and offers a positive seal and excellent adhesion to discourage pilfering. With a good balance of quick stick and holding properties, this tape can be used on all types of cartons. Performs well under a wide range of temperatures and humidity conditions. Complies with USPS requirements.
Foam Tape - Used extensively in the automotive, HVAC, and construction industries to provide air and weather-tight seals; for gasketing, cushioning, and vibration control in speakers, vehicles, electronic components, door frames, etc.
Foil Tape (Aluminum with Liner) - Used for vapor barrier protection, waterproof sealing, heat reflection, and masking in paint stripping and electroplating.
Foil Tape (Aluminum without Liner) - Used for waterproofing, vapor barrier and air leakage protection, metal patching, and sound dampening, as well as a sealing system in refrigerated appliances and microwave ovens. High reflectivity assures effective heat, light interference, and electrical insulation shielding.
Foil Tape (Copper) - Used for RFI/EMI shielding applications in the electrical/electronics industry.
Foil Tape (Lead) - Excellent adhesion to a wide variety of surfaces, especially to metal, glass, films, foils, and papers. Can be shaped to the most intricate patterns. Masking x-ray plates, electroplating, and chemical milling; radiation barrier, x-ray shielding; sealing double-paned windows; decorative leaded windows; weight balancing; electromagnetic and radio frequency shield.
Friction Tape - This woven cloth tape is also known as a cohesive fractioned cloth tape. Typically used for abrasion protection on wires and cables to cover electrical splices. Has excellent cohesion.
Gaffers Tape - Polyethylene-coated cloth laminated to a low gloss finish film, coated with a natural rubber-based adhesive. Conforms well to irregular surfaces and will not twist or curl during application. Excellent water, vapor, and abrasion resistance. Clean removal on most surfaces (surface type and dwell time may affect performance). Suitable for entertainment applications (concerts, trade shows, etc.) where minimal visibility of tape is desired. Used for holding down cables, wires, electrical cords, and marking placement on stages (i.e. “spike” tape). Suitable as a book binding tape for seaming and reinforcement.
Glass Cloth Tape - Conformable; chemical and solvent resistant, and printable. Used in strategic masking off areas for thermal spray/plasma spray applications. Also used for insulation of electrical apparatus and for sealing and bundling of non-electrical applications where flame retardancy or high heat resistance is required
Gummed Tape / WAT Tape - Gummed tape is a paper carton sealing tape, also known as water-activated tape (WAT), that when moistened, welds to the box it is being applied to, becoming part of the box. It bonds instantly to both virgin and recycled fiber surfaces and therefore, generates an immediate destructive bond resulting in a tamper-evident package. It is offered in both reinforced fiberglass and plain paper with many styles available in standard prints or customized prints.
Masking Film Tape - The two types of masking film tape are pre-taped and no tape. Pre-taped masking film has a strip of adhesive painter’s tape running along one edge of the film. The second kind has no tape, relying instead on the plastic’s static-cling properties to hold it in place.
Masking Tape (Painter's Tape) - Designed for superior performance in a variety of applications such as paint masking, holding, light-duty, splicing, bundling, packaging, and more.
Masking Tape (UV) - Provides clean removal characteristics and UV resistance – up to 14 days of outdoor exposure. A special characteristic of the adhesive system is that the peel adhesion does not increase with time, allowing for clean removal from a wide variety of surfaces without surface damage.
Pipe Wrap - Highly resistant to sun, water, oil, acids, alkalies, and corrosive chemicals. Bacteria, fungus, and abrasion resistant. Provides electrical protection. Protects pipe joints and conduit couplings for overhead or direct buried applications.
Polyimide Tape - Thin and conformable with outstanding tear and abrasion resistance at elevated temperatures. Adhesive will thermoset to increase adhesion values. Leaves minimal residue when removed after the manufacturing process, reduces clean-up time, and minimizes rejects. Permits observation of board during processing. Excellent resistance to acids, oils, solvents, aging, staining, and water immersion. Protects gold contacts from molten solder during the hot air wave solder leveling process.
Protection Film - Protection films are available in clear, blue, and black/white designs. This tape is manufactured for various surfaces and circumstances, including metal protection films for surfaces such as stainless steel and aluminum. Surface protection film for roofs and building materials including glass, tubs, sinks, and fiberglass.
PTFE Tape (Coated Glass) - Used as a primary insulation in a variety of electrical equipment and heat sealing bars, chute liners, gaskets, bearing surfaces, tabletop covers, guide rails, and roll covers. Low friction surface and abrasion resistance. Comes with a liner (WL) or available self-wound (SW).
PTFE Tape (Skived) - Used in electrical applications such as harness/coil wraps and separators, transformers, and slot liners where good insulation and heat resistance are required. Also used in mechanical applications such as heat sealing bars and jaws, labeling machine pressure pads, chute liners, anti-friction devices, bearings, forming dies, aircraft mold release, and guide rails where high temperature, maximum slip, and lubricity are required. High elongation permits tight wrapping and conforms to sharp bends/irregular surfaces.
PVC Tape - Used for secure attachment of extruded plastic profiles in furniture and general industries. Used extensively for mounting signs and large format graphics. Recommended for bonding trims in automotive and other industries.
Reflective Tape - Primarily designed for permanent and temporary traffic signage. Also used for work zone devices and non-critical signs where retroreflection is necessary.
Safety Tape (Non-Skid) - Non-skid safety tapes provide a high traction, anti-slip, and waterproof surface to help prevent slips and falls. Aggressive acrylic adhesive bonds to a variety of materials and conforms to irregular surfaces. For use indoors and outdoors, typically on walkways, ramps, stairways, machine shops, and work areas to comply with OSHA .263 (3).
Splicing/Printed Circuit Board Tape - Excellent resistance to solvents, heat, and chemicals. Used for component packaging and electrical insulation, edge reinforcement on books, webs, etc. Exhibits high resistance to abrasives, acids, oils, aging, staining, and water immersion.
Stucco Tape - A UV-resistant cloth duct tape used for protective masking of non-painted surfaces of various materials such as steel, vinyl, aluminum, and anodized metals. There is 50 percent more adhesive on this tape than the current best duct tape on the market.
Tamper Evident Tape - Carton sealing tapes that leave a security legend deposited on the box or container upon removal, discouraging tampering with and theft of the contents of the sealed cartons. Used in applications where high security is critical, such as pharmaceuticals, chemicals, medical equipment, crime evidence, independent labs, currency handlers, money bags, credit card/security bags, shipping and cargo handlers, transportation in food items, and products of high cost and/or high demand, such as electronics, clothing, and sporting goods.
Teflon Tape - Teflon tape, also known as thread seal tape, PTFE tape, or plumber’s tape, is a PTFE film for use in sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. Thread seal tape lubricates allowing for a deeper seating of the threads and it helps prevent the threads from seizing when being unscrewed. The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten, instead making it easier to tighten.
White – used on threads up to 3/8 inch
Yellow – used on threads 1/2 inch to 2 inches, often labeled “gas tape”
Pink – used on threads 1/2 inch to 2 inches, safe for propane and other hydrocarbon fuels
Green – oil-free PTFE is used on oxygen lines and some specific medical gasses
Gray – contains nickel, anti-seizing, anti-galling, and anti-corrosion, used for stainless pipes
Copper – contains copper granules and is certified as a thread lubricant but not a sealer
UHMW Tape - This tape has high chemical and abrasion resistance and extremely low coefficient of friction making this tape a top choice for many severe service applications. Materials slide freely over tape surfaces with no slip/stick tendency. High impact strength and shock-absorbing properties. Outwears Teflon and is a good replacement when high-temperature resistance is not a requirement. Rub strips on conveyors, bearings and sliding surfaces, chutes and hopper liners, dead plates, wear pads, guide rails, furniture, and drawer slides. Used primarily in automotive and mechanical applications.
Ultra High Bond Tape - Excellent all-around bonding properties and unique characteristics allow for very high performance in the most demanding of applications. The pressure-sensitive acrylic composition provides for very good tack, excellent adhesion to a variety of surfaces, and high shear strength performance.
Vinyl Tape - Used for color coding, lane marking, and safety coding to meet OSHA requirements. Also used for decorating, striping on vehicles, boats, sporting equipment, and other uses. Masking for hard chrome plating and anodizing, harness, pipe wrapping, duct, and joint sealing. Has a long shelf-life and “write-on” capability. It provides a very effective vapor and moisture barrier. It is highly conformable and resistant to aging, sun, water, fungus, bacteria, oil, acids, alkalies, and corrosive chemicals. It provides good abrasion, impact, and rupture resistance.
In this comprehensive guide to all things adhesive tape, we’re sharing 45 years of experience with you. Read on to find out why adhesive tape is quickly replacing glues and fasteners in manufacturing and construction, and how you can use it on your project today.
Adhesive tape (a.k.a. pressure sensitive tape, PSA tape, self-stick tape, or sticky tape) consists of a pressure-sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil.
Some tapes have removable release liners that protect the adhesive until the liner is removed. Some have layers of adhesives, primers, easy release materials, filaments, printing, etc. made for specific functions.
Pressure-sensitive adhesives (PSAs) do not require water, solvent, or heat activation to bond to materials such as paper, plastic, glass, wood, cement, and metal.
PSA tapes are tacky at room temperature in dry form, and they adhere firmly to a variety of surfaces and require only the application of a finger or hand. Technically speaking, that’s a bonding pressure of 14.5 – 29 psi =^ 10 – 20 N/cm² or greater.
Single-sided tapes allow bonding to a surface or joining of two adjacent or overlapping materials. Double-sided tape (adhesive on both sides) allows the joining of two items back-to-back.
The history of stickiness didn’t start with tape. It’s credited to the bees. Or rather, woodworkers in ancient Egypt used glue made from natural, viscous substances like beeswax and resin to hold materials together.
In modern times before tape, glues and epoxies did most of the sticky work. But they had serious drawbacks, especially in household use. Messiness, permanence, and drying to a hard finish all made traditional glues less-than-ideal.
It wasn’t until that adhesive tape, as we know it today, was invented.
According to How Stuff Works:

“Masking tape, as it became known, was intended to solve a very specific problem: applying two-toned paint jobs to cars. Before masking tape, auto shops were “masking off” for each color application using glue and paper. Peeling off the paper ruined countless paint jobs. Richard Drew, a young research assistant, witnessed one such ruined job and the furious cursing that followed. Drew, who had absolutely zero experience in adhesives, decided, apparently on the spot, to create an adhesive that could be removed from dry paint without peeling it off. Two years later, masking tape was introduced.”
Today, adhesive tape comes in all shapes and sizes, with varying degrees of stickiness, and for close to 45 years, ECHOtape has helped our customers match their specific application needs with the right pressure-sensitive tape.
And in that time, we have found that the majority of people have the same complaints and questions about tape. Here’s almost everything you need to know about adhesive tape as an industry professional.
We could tell you how adhesive tape is made, but this video by The Science Channel is much more fun:
https://www.youtube.com/watch?v=Y3N-MfmSAPg
As an aside, this video is also a great example of how tape is used in splicing. But that’s another topic for another time.
While the adhesive used on pressure-sensitive tapes might seem alike – they are all tacky, adhere well, and resist stresses – they are actually quite different. There are pros and cons for each tape type, be it rubber/resin, synthetic rubber, acrylic, and silicone-based adhesives.
Rubber/Resin is the oldest type of adhesive based on natural rubber, but it needs a resin to make it into an adhesive.
For many jobs, rubber/resin adhesives offer many advantages:
When it comes to disadvantages, rubber/resin’s main weakness is that both the rubber and the resin are prone to oxidation from the air. Therefore, exposure to ultraviolet light from the sun and other light sources can break down in heat.
Synthetic Rubber can be used in place of natural rubber. Offering much higher adhesion and shear resistance than natural rubber-based adhesives; as a result, it is very good for sealing packages and cartons.
Acrylic Adhesives Most of the weaknesses of rubber/resin adhesives are overcome by a single component of pressure-sensitive adhesive based on “acrylic” chemistry. Acrylic is colorless and is stable to oxidation and exposure to ultraviolet light. The stability to oxidation can give an acrylic adhesive tape many years of protection against ultraviolet light. However, it is more expensive – about twice as much as rubber/resins; it’s not quite so good as natural rubber on harder-to-adhere surfaces, and it needs significant time to cure.
Silicone-based Adhesives give many years of service life. Like acrylics, silicone can be used against the skin, so it has many medical applications as well as uses in the electrical industry where temperature is a challenge (e.g., jet engines). Silicone adhesives and sealants have a high degree of flexibility and are resistant to very high temperatures. However, silicones are the most expensive adhesives of all, typically twice as much as acrylics.
Traditional adhesives essentially transform from a liquid form into a solid one to adhere. Those processes are a function of the type of adhesive and how it is engineered to work and for what purpose. The interesting aspect of pressure-sensitive tapes is that they are “just liquid enough” to sufficiently wet the surface the tape contacts.
Conversely, these pressure-sensitive adhesives have enough of a solid-state character to resist any forces trying to remove it. As a result, pressure-sensitive adhesive tapes deliver the ideal means of fastening and offer the following significant advantages:
We get this question a lot: How do we actually know that it’s the right tape for the application and that it’s going to last? And that’s totally fair.
Almost everyone we know has a tape failure story, but tape isn’t the same as what you grew up with, or even what you used five years ago. Just as the cell in your pocket has gotten smaller, faster and smarter, adhesive technology has gotten stronger and more versatile.
On a job site full of tools and specialty equipment, tape may seem as ubiquitous as a hammer and nails. However, nothing beats tape for versatility, portability, and ease of use… that is IF you have the right tape for the job at hand. And that’s the conundrum, isn’t it? The sheer volume of pressure-sensitive adhesives is so overwhelming that it’s hard to know where to begin.
To help, we’ve created an infographic as a portable field guide for builders and contractors. You can find it here:
When it comes to tape, you may think you can’t believe everything you read. Upon review, a tape’s specification sheet can indicate that its adhesive properties are good, but when you use it, the resulting adhesion is poor.
Of course, when this happens, the tape tends to get the blame. But it isn’t always your tape for example that is at fault. In fact, it may be the surrounding conditions or even the surface that you are trying to stick the tape to.
If you’re facing this challenge, carefully consider every condition that could affect your tape. These can include several variables:
Carefully factor in the temperature. Are both the tape and the surface at least 18ºC/65ºF? The tackiness of the adhesive tape is very temperature-dependent, and the colder the conditions, the poorer the bond will be. If you must work at lower temperatures, then use an adhesive tape specifically designed for colder climates.

Surface: Is the surface clean? Traces of dust, dirt, grease, and even the slightest trace of moisture will contaminate the adhesive surface and act as a barrier between the two. To best prepare, the surface, give it a quick wash with rubbing alcohol and dry it with a clean cloth.
The typical adhesive tape has a very thin, flat smooth layer of adhesive. Is your surface also flat and smooth, so that the two can uniformly contact one another? If your surface is rough and full of micro “hills and valleys,” the tape can only make contact at the high points – which will result in a weak bond. With a moderately rough surface, you will need a tape with a much thicker adhesive that can fill these valleys, thus providing a major improvement in contact. If it is too rough, then you may need a foam tape with enough deformation to make a good bond.
Is the surface you are working with a plastic or other material? Is it covered with paint or another coating that has a naturally low adhesion or even release quality? Regular adhesive tape won’t stick to waxed surfaces, Teflon®, or silicone, and will even have difficulty sticking to polyethylene. A very tacky tape will help, as well as tapes with an adhesive that is based on natural rubber, but you may need to turn to an adhesive tape specifically designed for your specific surface.
As a very last resort, you may need to change the character of your surface to get an adhesive tape to stick to it. This could mean roughening it with an abrasive or even treating it with a prime coat that is compatible with both the surface and the adhesive.
When a customer comes to us with a challenge, we actually test the tape for them and with them.
There are two ways to do this: Real-world field testing and lab testing. Ideally, we get to do both, like at The Durability Lab, but the bottom line is that the real world test matters most.
What good is a lab report when your building envelope leaks like a sieve, or your flying splice failed because the adhesive didn’t stick fast enough? Not good at all.
So here we’re going to walk you through the most common tape testing variables we use at ECHOtape.
One of the most critical aspects of our application trials is to test the tape on the actual substrate which is where real-world applications come into play.
For years, lab tape testing was performed on standardized substrates, like steel, and it did not differentiate performance based on a specific material. Over the last five decades, we have learned how critical a factor this is. The tape may work on one specific substrate and fail on others. Sometimes the tape works on a substrate, but when any changes to the chemistry or condition of the substrate change, the tape could end up failing. Even a small change can have a major effect.
Take, for example, splicing tapes. In many situations, customers need a quick stick while materials are still moving (called a flying splice), but then the tape needs to permanently adhere for long-term performance. We first test splicing tape by hand on the substrate — paper, cardboard, flexographic materials — and then see if it pulls fibers. This is good because this shows that the tape has a quick stick. Then, we move it to the actual machine for real-world testing. A splice can take a blink of an eye and so you need to test the tape in the manufacturing process
Which one you want makes a difference in how you test tape. Here are some more behind-the-scenes insights to our application testing process.
For temporary bonding, we are trying to discover whether tape adheres quickly and comes off cleanly..an important field test when considering protective film or stucco tape. In this scenario, we will apply the same environmental conditions to the adhesives, and see how it performs. Does it apply quickly and evenly? Does it remove easily and without residue? We can certainly duplicate this in the lab, but there’s no replacement for real world testing. Which is why it’s important that our clients understand that field tape testing takes time. If your issue is stucco tape isn’t sticking in 90°F and 100% humidity, it doesn’t do us any good to test it in the fall when it’s 60°F and 20% humidity.
Permanent bonding is a different animal. Oftentimes, the tape needs to cure to assess performance, like acrylic adhesives that need 72 hours to set. There are two common real-world tests we use here:
UV light is a type of electromagnetic radiation, as are radio waves, infrared radiation, X-rays and gamma rays. It’s invisible to the human eye, but it makes a profound effect on adhesives. With prolonged exposure to ultraviolet light, certain chemical materials, such as natural and some synthetic rubbers as well as polyethylene, can experience negative changes to their properties; resulting in them becoming hard and brittle. Absolutely not the qualities you want in a tape that needs to hold for any duration in a particular application. (Read our behind the scenes report on The Durability Lab here.)
The good news is that you can minimize the effects of UV light by choosing the right tape. For outdoor use, it is best to stay away from adhesive tapes with a natural or synthetic rubber adhesive. Unless the adhesive has been specially treated with ultraviolet stabilizers or the backing has an ultraviolet light barrier, like a premium outdoor stucco duct tape. There are also adhesive tapes that have been specially designed for prolonged outdoor exposure typically using an acrylic adhesive.
We are the leaders in cold weather tape for good reason: our home offices in Canada are ground zero for sub-freezing environmental conditions.
It doesn’t get any more real than that.
Still, we do also conduct lab testing. Using a temperature-controlled, environmental chamber, we bring temperatures down below -30°F and assess the outcome. Does it stick, and does it stay secure? The same is true for heat, although real-world tape testing is done in Arizona, Florida, and Texas.
For engineers and general contractors, both the tape sample and the specification sheet should be closely reviewed when considering their uses. But what detail does the specification sheet provide and how can the maximum benefit be derived? Here’s what you need to look for, whether it’s high-bond foam tape, stucco tape or industrial-strength construction-grade duct tape:
Tapes are often rated by adhesion value, which can be helpful if you know what it means. Here are a few examples:
When it comes to determining if a particular tape is right for your construction project, there are two forces to consider: tensile force and shear force.
Tensile force influences the elastic property of the adhesive. Specifically, it will first stretch the adhesive before finally pulling it away from the surface. If a tensile force causes a failure, it will most likely be in the adhesive at the surface. Therefore, adhesion testing that measures the elastic character of the adhesive, and how much force it can take, will help you select the right tape.
A shear force works parallel to the surface – it is the major force at work in double-sided tapes. Shear force resistance testing – often called “Holding Power” – is an effective way to measure the internal strength of the adhesive (known as “cohesion”).
Most adhesive failures or separation occur as a combination of both tensile and shear forces, it is extremely helpful to know what forces could potentially affect your tape.
Keep in mind that if the outside force is large enough, and is continuously applied, all tapes will eventually fail. It’s not a matter of “if,” but “when” – it may take an hour, a week, a year, or more, but if a tape isn’t designed to withstand the outside forces, it will eventually fail.
For tape, because of how it is dispensed, the adhesive part must contact its own backing yet still be able to unwind easily. To achieve this, the backing must provide a low-adhesion release surface. In other words…not stick to itself!
For all of the above, the best solution is to use a facing material with a low surface energy, usually a paper or a plastic film that has been treated with a silicone release coat. They could also be a polyethylene film that already has a low enough surface energy to work as release facing, or even a silicone-coated polyester film.
In short, pressure-sensitive adhesive tape is the industrialist’s dream come true. It is the universal tool that simply and conveniently solves many different fastening challenges. These tapes come in a wide variety of backings, each suitable for specific end-uses. This is exactly why adhesive tape use is on the rise in high-performance building and construction. If you’re still using glues, sealants or even nails, consider pressure-sensitive tape.
