Coating System for Girth Weld Coating, Coating of Fitting, Coating Repair –Joint wrap
T300 series are 2-Ply polyethylene (PE) anticorrosive adhesive tapes. It is Cold wrap tape coating system for Girth Weld Coating, Coating of Fitting, Coating Repair. In order to promote high adhesion of the coating system to the pipe, the more higher Solid content primer is recommended. More Primer Solid content , providing maximum handling for the coating system with PE tapes.
Features:
Heavy duty adhesive
Resistant to UV
Can be applied over a wide temperature range
Easily applied with no special equipment
Conformable to irregular shapes.
Meets ASTM D 1000 Standard
Cold applied
BR-Buty-Rubber basic adhesive
BC- Butyl Bitumen compound adhesive
