The Tesa 7074 is a black acrylic foam tape. It consists of a high-performance acrylic system, and due to its unique components, it combines a very good temperature resistance with an outstanding cold shock resistance. It is designed for demanding outdoor bonding applications, especially in combination with the Tesa adhesion promoters. The visco-elastic, foamed acrylic core compensates different thermal elongation of bonded parts. Bonding of panels and reinforcement bars in the following Industries: elevator, solar, transportation, production equipment. Foamed acrylic backing material. 1000 micrometers total thickness. Pure acrylic adhesive. 1000 percent elongation at break. Adhesion to steel (initial): 12 N/cm; aluminum (initial): 10 N/cm; glass (initial): 20 N/cm; steel (after 3 days): 30 N/cm; aluminum (after 3 days): 25 N/cm; glass (after 3 days): 32 N/cm. Medium tack, very good ageing resistance (UV), very good humidity resistance, very good resistance to chemicals, medium softener resistance, very good static shear resistance at 73.4 degree F, very good static shear resistance at 158 degree F, very good T-block.
