What is Tesa 7805?
Tesa 7805 is a high-performance double-sided acrylic foam tape, designed for reliable bonding in demanding environments. Its viscoelastic acrylic foam core allows it to absorb and redistribute static and dynamic shear forces, while its modified acrylic adhesive ensures high initial tack and long-term adhesion, even on difficult surfaces. Thanks to its cold shock resistance and sealed foam structure, Tesa 7805 maintains strong and durable bonds in both extreme cold and moisture-exposed conditions. Its thin 0.5mm profile makes it suitable for discreet bonding applications that require a sleek appearance.
