Product description

tesa® 51970 is a transparent, double-sided industrial mounting tape with a highly tackified adhesive and PP backing. The double-sided PP film tape is used in various different industries, frequently for mounting plastic or wooden trims or fastening signs and point-of-sale displays. The tackified acrylic adhesive features excellent adhesive performance, offering a reliable bond, often also on low energy surfaces and rough or slightly dirty substrates. tesa® 51970 is able to withstand numerous environmental factors such as humidity, UV light, and temperatures of up to 130°C for limited periods of time. The tackified acrylic adhesive offers excellent hold on various surfaces, very high tack, and good shear strength.
