Corrosion protection Viscoelastic Tape definition: Viscoelasticis a new-type high-performance visco elastic polyolefin material. CYG Viscoelastic Tape is mainly designed for corrosion protection.
CYG flange corrosion protection Viscoelastic Tape enjoys the propertiers of both solid adhesive material and the liquid adhesive material.
Application of viscoelastic :It is designed for pipeline joint coating, repair, anti-corrosive for elbow, winding pipe, tees, insulating flange ect.
Service Life ofviscoelastic : excellent viscoelastic , sound water-proof and easy-installation characters.
Viscoelastic tapefeatures:
Viscoelastic can be use in the surface of steel, PE, PP, FBE etc. directly.
Completely compatible to other coating (three-layer PE, CTE-coating, asphaltum)
Excellent chemical resistance and sealing, it is completely water-proof.
Viscoelastic tape enjoys the property of self-repair for light defects.
Widely applicable temperature (it can be installed between-30°C~60°C).
The Construction Quality can be handled. viscoelasticity seldom affected by the environment and the operator.
viscoelastic tape can be stored in long time and the material it adopts is eco-friendly.
