Waterproof Pure Polyurea Material

Polyurea waterproof Coating, Spray Polyured Waterproofing Coating) is the introduction of foreign advanced technology, combined with the domestic research and development of key project construction technology requirements of a no solvent, no pollution, high reaction type of protective Coating.

This product is A kind of two components, A, B, solvent-free, fast curing green elastic waterproof material, on the basis of film forming different reactive groups are divided into play high spraying polyurea (plain) (JNC) and high elastic waterproof coating spray polyurethane (urea) (commonly known as half polyurea elastic waterproof coating,), divided into Ⅰ and Ⅱ according to physical properties. Components A and B are mixed and ejected in the spray gun of special spraying equipment, and the elastomer waterproof film is formed by rapid reaction curing.

A component of high-spray (pure) polyurea waterproof coating is A semi-prepolymer prepared by reaction of hydroxyl compound and isocyanate. Component B is a mixture of end-amino resins and end-amino chain extenders, and shall not contain any hydroxyl component or catalyst, but shall contain a small amount of pigment and dispersed auxiliaries. A component of elastic waterproofing coating with high-elastic spraying polyurethane (urea)(commonly known as semi-polyurea) is A semi-prepolymer prepared by reaction of hydroxyl compound and isocyanate. Component B is a mixture of hydroxyl terminated resin or amino-terminated resin and amino-terminated chain extender. In component B, a catalyst may be used to enhance the reactivity, and a small amount of pigment and dispersing auxiliaries may be permitted.

This product is required when the film is made of special professional construction machinery coating forming, its excellent physical and chemical performance, convenient construction technology, anti-water system integrity, as well as the environmental protection is a kind of traditional protective materials and any other technical reach, is widely used in urban subway, high speed railway bridge, tunnel, water conservancy machinery, Marine chemical, waterproof, anti-corrosion, wear resistance of dual-use items "two a resistant to" project.

Suitable for the national key project of building, metal tank and pipeline inside and outside surface of all concrete surface "two a resistant to" (waterproof, anti-corrosion, wear-resistant) subdivisional work, has been widely used in urban subway, high speed railway bridge, tunnel, water conservancy machinery, petrochemical industry, Marine engineering such as drilling, dual-use.
