If you are looking for China golden supplier and China good supplier white polyken 955-20 mechanic protection tape, good quality and high quality steel pipeline coating tape, please feel free to contact Jining Qiangke Pipe Anticorrosion Materials Co.,Ltd.
System Description
The white polyken 955-20 mechanic protection 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. Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground or overhead pipelines. The outer-layer tape backing shall be compounded so that it will be resistance to outdoor weathering.
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.The Middle and Outer Mechanical Protection Layers provide exceptional handling and in-service protection of the coating system.
The Middle and Outer Mechanical Protection Layers provide exceptional handling and in-service protection of the coating system.
