Self-adhesive bitumen waterproof tape
Description
Qiangke 934 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 Polyken934 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
Structure
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
Features
_ Excellent adhesion to pipe and self _ Flexibility provides extra protection at vulnerable areas _ Excellent conformability and consistent uniform thickness _ Easily applied with no special equipment _ Compatible with common pipe coatings _ Excellent resistance to cathodic disbonding | -Resistant to UV _ Can be applied over a wide temperature range _ Good conformability and consistent uniform thickness _ Cold applied _ Heavy duty butyl bitumen compound adhesive ensures a strong bond & impervious seal. |
