Visco-Elastic Coating


Visco-Elastic Coating

CYG visco-elastic coating consists of new-type high-performance visco-elastic polyolefin materials. visco-elastic tape combines the characteristics of both solid and liquid adhesive materials into one. The property of  CYG visco-elastic coating will last more than 30 years under normal conditions.

Visco-elastic coating are used in many fields from pipelines to subsea piles, from rail to cable joint protection. Especially for irregular objects, such as Tee joint, flange, valves corrosion protection.

Visco-Elastic Sealant coating features:

Simple surface preparation and directly applied on steel, PE, PP, FBE without primer.
Compatible to 3LPE, CTE-coating and asphalt.
Excellent impermeability to water and oxygen.
Perfect chemical resistance.
Self-healing for general coating defects.
Applicable to field joint coating and repair of damaged coating on pipeline as well as any shape fittings such as elbow, bend, T-joint and insulated flange.
Applicable temperature-30℃~60℃.
Controllable construction quality and seldom affected by environment and operator skill.

An eco-friendly material to be stored for a long time.
