Traditionally, the only way to attach anything was with nails and screws. These are known as mechanical fasteners. Screws, nails, rivets, welds and even liquid adhesives fall under the category of conventional bonding methods. Acrylic foam tape, often referred to as VHB™ tape or Very High Bond tape, offers several advantages over traditional bonding methods and can be used instead of screws and nails.
High Bond Acrylic Foam Tape is safe, quick and easy to applyMechanical fasteners require time, labor and money to apply as well as additional tools and skill. Because VHB™ comparable tape utilizes a pressure sensitive adhesive (also referred to as PSA), it is fast and easy to apply simply by peeling back the liner and administering pressure. No drilling, welding or other time-consuming, noisy, and disruptive processes are required. Acrylic foam tape also has advantages over liquid adhesives. For example, liquids are messy and may give off unpleasant and even harmful fumes. VHB™ tape alternative has no odor and doesn’t give off harmful chemicals. The only cleanup involved in using acrylic foam tape is discarding the liner.
Very High Bond Tape compensates for irregularities between bonded surfacesIdeally, bonded materials should be perfectly flat against one another and never move or shift. However, this is rarely the case. Uneven surface textures, changing temperature effects like thermal expansion, and chemical reactions are some major factors that can affect a solid bond.
Often times, you need to bond two very different materials to one another. For example: Metal and glass, concrete and metal, plastic and glass, or vinyl and wood. Acrylic foam tape conforms to irregular surfaces and compensates for gaps and spaces between materials.
Expansion and Contraction
Thermal expansion is a natural occurrence that takes place when temperatures rise. Likewise, materials also contract in colder temperatures. Both of these natural changes can create tension against the bond between two components. High bond tape is constructed of a high mass acrylic adhesive that allows for expansion and irregularities without weakening or breaking the bond. Acrylic foam tape also has a viscoelastic structure that conforms and adapts to environmental changes like thermal expansion, temperature extremes and structural settling.
Metal on Metal Corrosion
Bimetallic corrosion is the accelerated deterioration of one metal when placed in contact with another. The full surface coverage offered by traditional VHB™ tapes acts as a buffer between two metals that may otherwise corrode or produce chemical reactions with one another. Acrylic foam tape will not rust or suffer from other natural chemical reactions found in various metals and may prevent these changes from affecting conjoining surfaces.
No stress points = A stronger bondScrews, nails, and welds create stress points. In typical construction, fasteners like screws, nails or welds are inserted periodically across the length of the desired bond. These pressure points can become weak, rusty or stressed and eventually break. Acrylic foam tape distributes stress evenly across the entire joined surface, eliminating uneven stress points and providing a stronger, more secure bond.
Acrylic Foam Tape provides a seamless appearanceWhen a seamless line is necessary (or simply preferred for aesthetic), VHB™ tape alternative offers a clean, smooth appearance as opposed to several weld points or screws across an otherwise flat surface. Traditional bonding methods can interrupt the design of a truck body or a building facade for example. Acrylic foam tape maintains a smooth and seamless bond without affecting the exterior appearance. VHB™ comparable tape is an excellent choice for decorative attachments.
Very High Bond tape absorbs impact, vibration and noiseAcrylic foam tapes possess shock and vibration damping qualities that mechanical fasteners simply do not. Very high bond tape's acrylic mass delivers exceptional noise reduction by cushioning and eliminating contact between two substrates. High bond tape absorbs impacts and rattling created by static and dynamic loads in transit, during machine operation or through exposure to extreme weather and other environmental conditions. With screws, nails and other fasteners, an additional material or separate buffer would be required to control rattling and friction between materials.
