white polyken 955 pipe outer wrap tape
Mar 05, 2016



System Description

The white polyken 955 pipe outer wrap tape is a multilayer system used for the protection of steel pipelines. They are designed for machine or brush application and 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 POLYKEN 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.The POLYKEN 980/955 can also be used for ductile iron pipes, in this case the use of 1027 primer is recommended.
