tesa® 4970
Double-sided filmic tape with high adhesion
Product description
tesa® 4970 is a thick, white, double sided self-adhesive tape consisting of a PVC-film backing and a tackified acrylic adhesive. The strong double sided tape features an excellent combination of high tack and immediate adhesion. Moreover, the acrylic adhesive offers a high coating weight, ensuring excellent bonding performance on rough or dusty surfaces. tesa® 4970 tape is highly resistant to humidity, light and natural ageing. It can also withstand numerous chemicals, water and softeners. It has a short-term temperature resistance of up to 70°C and a long-term resistance of up to 60°C. Due to its durability, tesa® 4970 is suitable for demanding, long-term and outdoor applications.
