Description

Guanfang 934 Cold applied tape coating system designed for the corrosion protection of field joints, fittings, and specialty piping&waterproofing. The highly conformable backing and thick, aggressive adhesive also make it the ideal repair system for all types of main line coatings.

It could be applied after the primer by hand or with a wrapping machine

Structure

The specification of the tape consists of three layers,

Backing:Special blend of stabilized polyolefines

Adhesive:Butyl rubber Bituminous Compound and Adhesion Promoting Resins

Interleaf:Antiadhesive Film Treated with Silicone
