POLYKEN 955-25


The polyken 980/955 is a multilayer system used for the protection of steel pipelines. Polyken 1019, 1027 1033A or 1039 Liquid adhesives can be used as primers for this system. In addition to serving as primers, these liquid adhesives themselves represent an anticorrosion 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 formulated with stess-corrosion cracking inhibitors. The anti-Corrosion layer Polyken 980 is engineerid to assure a high bond to the primed surface with the excellent conformability chracteristics. The mechanical protection layer Polyken 955, achives 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 system contain proven anti-microball additives. The Polyken 980/955 can also be used for ductile iron pippes, in this case the use of 1027 primer is recommended.
