VHB Tape 4952 is a soft, extra conformable, double-sided, pressure-sensitive, closed-cell acrylic foam tape with a polyethylene film liner.
The foam carrier used provides the highest level of conformability to irregular surfaces, while maintaining high internal strength.
It is especially suitable for applications where one, or both, substrates are flexible, although it also works equally well with rigid substrates
With a modified acrylic adhesive, 5952 bonds to many high surface energy (adhesive friendly) substrates - such as metals, glass, painted or sealed wood, concrete, and painted or powder-coated surfaces.
It exhibits medium adhesion to low surface energy plastics such as rigid PVC, polystyrene, ABS, acrylics (such as Plexiglas®), and polycarbonates (such as Lexan®).
Do not use on platicized vinyl.
Among 3M's VHB tapes, 4952 adheres to the broadest range of substrates.
VHB Tapes combine the strength of a mechanical fastener with the convenience and simplicity of a tape.
They form instant, permanent bonds with no drying time, no mess, and are a convenient and proven alternative to nails, screws, or rivets.
As always, especially for critical applications, test this product for suitability under actual application conditions prior to using.
• A conformable foam tape suitable for bonding to flexible or somewhat irregular surfaces
• 45 mil thick without liner
• High strength, durable adhesion to high surface energy materials
• Medium adhesion to certain low surface energy plastics
• High solvent resistance
• Temperature range: 250°F (300°F for short periods)
• 5 mil, red polyethylene liner
• UL listing 746C
• Note that VHB Tapes typically have low resistance to UV degradation. When used outdoors, and particularly in glazing applications - as they commonly are - they must be protected by a frit or other UV barrier
For a VHB tape with higher adhesion to low surface energy substrates, 3M offers VHB 4932 (25 mil) and VHB 4952 (45 mil) which are firm foam tapes suitable for flat rigid surfaces.
Heavy on the technical side...
3M&trade VHB Tapes are high-strength, structural bonding tapes.
They are a proven and convenient alternative to screws, rivets, welds, and other mechanical fasteners.
Unlike screws or rivets - which join materials at a single point - high-strength bonding tape permanently adheres one substrate to another while spreading the stress load across the entire length of the joint.
Comprised of closed cell foam impregnated with extremely high-strength pressure sensitive adhesive on both sides, the tape's flexibility allows it to compensate for differential thermal expansion between dissimilar materials — so they can be bonded with confidence.
Very High Bonding tapes feature instant bonding, and once materials are joined with VHB&trade Tape a virtually indestructible "weld" is created.
Skyscrapers, cell phones, highway signs, refrigerators, marine electronics, architectural windows, recreational vehicles… all of these rely on specialty VHB bonding tapes for one or more steps in their assembly, mounting, fastening, or sealing.
