PE Inner Anti-corrosioin Tapes (T100)
Coating System for pipelines-Inner Layer:
T100 series are 2-Ply polyethylene (PE) anticorrosive adhesive tapes. It is Cold wrap tape coating system for Corrosion Protection of Water, Oil and Gas Pipelines. The inner-layer tape shall be applied after the Primer and before the Outer-layer tape. 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:
Excellent adhesion to pipe and self.
Can be applied over a wide temperature range .
Good conformability and consistent uniform thickness.
Easily applied with no special equipment.
Compatible with common pipe coatings.
Excellent resistance to cathodic disbonding.
Meets ASTM D 1000 Standard.
Cold applied.
