The 4991 VHB tape offers design flexibility with its viscoelasticity and powerful ability to bond to a variety of high and medium surface energy substrates. This bonding tapes provide excellent shear strength, conformability, surface adhesion and temperature resistance
This family utilises multi-purpose acrylic adhesive on both sides of a conformable adhesive foam core. The adhesive provides excellent adhesion to a broad range of high and medium surface energy substrates including metals, glass, and a wide variety of plastics, as well as plasticized vinyl. The conformable adhesive foam core provides good contact, even with mismatched substrates.
Fast and easy-to-use permanent bonding method provides high strength and long-term durability
Pressure sensitive adhesive bonds on contact to provide immediate handling strength
