Product Description

Product Description:
A two-component, fast-reacting spray polyurea system. The cured polyurea coating has excellent physical and mechanical properties, outstanding corrosion resistance and weather resistance.

Application Scope:
Anticorrosion and protection of the inner and outer walls of buried metal pipelines (such as, oil transportation pipelines, natural gas pipelines, tap water pipelines, gas pipelines, etc.).
Integral sealing, joint sealing and welding seam protection of various buried pipelines.

Advantages:
The coating has strong adhesion, and it wraps the pipeline seamlessly and tightly as a whole, forming a permanent anti-corrosion protection layer on the outer wall of the pipeline.
Excellent corrosion resistance and weather resistance make it able to adopt to environmental temperature changes from -40°C to 150°C.
High strength, impact resistance, tear resistance, abrasion resistance, waterproof and impermeability.
Curing speed is very fast and can be sprayed continuously on any curved surface without sagging, and the film thickness is uniform, effectively avoiding missing coating.
The construction efficiency is very high. It only takes 1 hour to coat the outer wall of 200m² pipeline, and can be buried underground in 30 minutes.
Solvent-free and environmentally-friendly.
