System Description

Butyl rubber Waterproof Sealing tape is made of saturated butene rubber, butyl rubber elastic plastic rubber, halogenated butyl rubber as the main raw material. These products have excellent air tightness, water tightness, good self-adhesive, elongation, weatherability, low temperature resistance and water resistance, no solvent pollution, that is, adhesion, construction safety and convenience. Can be widely used in polymer waterproofing. Butyl rubber Waterproof Sealant adhesive tape has a strong adhesion to the surface of various materials, with excellent weathering resistance, anti-aging and waterproof, the adhesive surface to seal, damping, protection and other functions. The product is totally free of solvent, so it does not shrink, does not emit toxic gases. Because its lifetime is not curing, so the heat shrinkage and mechanical deformation of the surface has excellent adhesion, is a very advanced waterproof sealing material.

Features

-Resistant to soil stress - Excellent adhesion to pipe and self -Low cathodic protection -Long-term in-ground performance - Serve for low-high temperatures

- Cold applied -Uniform coating thickness -Compatible with all pipe diameters and generic plant coating systems -Qualified ASTM D1000,AWWA C 214,EN 12068 standards
