POLYKEN 980 Anticorrosion Tapes(Inner Wrap)

POLYKEN 980&955

Cold Applied Tape Coating System

System Description

The POLYKEN® 980,955 is a multilayer system used for the protection of steel pipelines. POLYKEN® 1019,1027 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 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 POLYKEN® 1027 primer is recommended.

Material Calculation Formula :

(Width of Coating in inches) ×(Area of pipe in square feet)*

----------------------------------------------------------------------------=Squares **of Coating Required

(Width of coating in inches-Overlap in inches) ×100

*Area of pipe in square feet=(Diameter in inches)/12×3.1416×(Length in feet)

**One square=One hundred square feet=9.29 square meters

(Width of Coating in mm) ×(Area of pipe in square meter)*

-------------------------------------------------------------------------------=Square meter of Coating Required

(Width of coating in mm-Overlap in mm)

*Area of pipe in square meter=(Diameter in mm)/1000×3.1416×(Length in meter)
