Details:

Coating System for Girth Weld Coating, Coating of Fitting, Coating Repair –Joint wrap 

T300 series are 2Ply 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.
