System Description
The pipe double sided tape is a cold applied tape used for the corrosion protection oil , gas ,water underground or overhead pipeline . It is also called double sided butyl rubber anti-corrosion tape.
The XUNDA liquid adhesive can be used as primer for this tape. The liquid adhesive represent an anti corrosion layer and provide a uniformly smooth contact surface to promote high adhesion of double sided tape to the pipe .
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
