tesa® 4957

Double-sided PE-foam mounting tape

Product description

tesa® 4957 is a double-sided PE-foam tape for general mounting applications. It consists of a highly conformable PE-foam backing and a tackified acrylic adhesive. tesa® 4957 has been externally certified for window bar mounting.

Product benefits:

Versatile adhesive for high immediate adhesion on numerous substrates
Fully outdoor suitable: UV, water and ageing resistant
Compensates for differing thermal expansion of dissimilar materials
High immediate bonding strength even at low bonding pressure
Very good cold shock absorbtion
