Polyethylene tape for burried pipelines

Polyken 980 955 coating system is a multilayer system used for the protection of steel pipelines.Polyken #1019, 1027, Liquid Adhesives can be used as primers. In addition to serving as primers, these liquid adhesives themselves represent an anti-corrosion layer and provide a uniformly smooth contact surface to promote high adhesion of the coating system to the pipe. They are designed for machine or brush application and are formulated with stress-corrosion cracking inhibitors.

The Anti-Corrosion layer Polyken #980 is engineered to assure a high bond to the primed surface with excellent conformability characteristics.The mechanical protection layer Polyken #955, achieves a complete bond to the #980 inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all Polyken tape systems contain proven anti-microbial additives.
