Viscoelastic anticorrosive tape is a new-type high-performance viscoelastic polyolefin material. It preserves the dual characteristics of the solid adhesive material and liquid adhesive material. In normal conditions, its viscoelastic property will keep above 30 years. This product has excellent viscoelastic , sound water-proof and easy-used characters.
Product feature:
It 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.
It can be self-repair for light defects.
It is useful to pipeline joint anticorrosion and repair, also for elbow pipe, pipe bending, three joints and insulated flange.
Widely applicable temperature(it can be installed between -30℃~60℃).
The Construction Quality can be handled. It seldom affects by the environment and the operator.
It can be stored in long time and the material it adopts is eco-friendly.
