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,
1027,
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.
