53Polyolefin anticorrosive tape
Item No.: Conet-54

The specification of the tape consists of three layers,
Backing:Special blend of stabilized polyolefines
Adhesive:Butyl rubber Bituminous Compound and Adhesion Promoting Resins
Interleaf:Antiadhesive Film Treated with Silicone 


Description

Polyolefin anticorrosive tape: Cold applied tape coating system designed for the corrosion protection of field joints, fittings, and specialty piping&waterproofing. The highly conformable backing and thick, aggressive adhesive also make it the ideal repair system for all types of main line coatings.
The tape with very tacky adhesive has a release plastic liner to enable proper unwinding of the roll. Whether used as a single wrap with a mechanical layer or a double wrap system, the 934 tape coating system is universally specified in the oil, gas and water industries
It could be applied after the primer by hand or with a wrapping machine.
