The double sided tape shall be applied after liquid adhesive and before the pipe protection tape.

Product Composition

The composition of the pipe wrap tape - double sided tape consists of four layers, internal adhesive layer,external adhesive layer , film backing and interleaving.

Internal adhesive : Butyl rubber

External adhesive : Butyl rubber

Film Backing: Special blend of stabilized polyethylene

Interleaving:Anti-adhesive film treated with silicone
