tesa 4965
Double-coated Tape with High Shear and
Temperature Resistance

Product Description/Application:

tesa 4965 is a transparent, double sided, self-adhesive tape consisting of a PET film backing and a modified acrylic adhesive.

tesa 4965 features esp.

reliable bond even to Low Surface Energy
substrates.
immediate usability right after as-sembly
suitability for most demanding ap-plications such
as heavy stress, high temperatures or critical
sub-strates

tesa 4965 is used for applications like.
