POLYKEN # 980 / 955
Line Travel Coating System
for Pipeline Protection


Thick, aggressive adhesive for corrosion protection
and repair of main line coatings.

System Description

The Polyken Line 980 / 955 Travel Coating System is a multilayer system used for the protection of steel pipelines. Polyken #1019, 1027, 1033A or 1039 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. See MSDS for 1019, MSDS for 1027, MSDS 1039 adhesives and primers.

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.
