What is the product description of polyurea waterproof coating?

Spray Polyured Waterproofing Coating is a solvent-free, non-polluting, highly reactive protective coating developed by introducing advanced foreign technology and combining the construction process requirements of key domestic projects.

This product is a two-component A, B, solvent-free, fast-curing green and environmentally friendly elastic waterproof material. According to the different film-forming reaction groups, it can be divided into high-elastic spraying (pure) polyurea waterproof coating (JNC) and high-elastic Spray polyurethane (urea) (commonly known as semi-polyurea) elastic waterproof coating (JNJ) is divided into type I and type II according to physical properties. The A and B components are mixed and sprayed in the spray gun of the special spraying equipment, and react and cure quickly to form an elastomer waterproof film.

High-elastic spraying (pure) polyurea waterproof coating A component is a semi-prepolymer prepared by the reaction of hydroxyl-terminated compound and isocyanate; B component is a mixture of amino-terminated resin and amino-terminated chain extender, and must not contain Any hydroxyl components and catalysts, but a small amount of pigments and dispersing additives are allowed. High-elastic spray polyurethane (urea) (commonly known as semi-polyurea) elastic waterproof coating component A is a semi-prepolymer prepared by the reaction of hydroxyl-terminated compounds and isocyanates; component B is hydroxyl-terminated resin or amino-terminated resin and amino-terminated expansion The mixture of chain agents can contain a catalyst for improving the reaction activity in the B component, and it is allowed to contain a small amount of pigments and dispersing additives.

This product needs to be sprayed and formed by special professional construction machinery when forming a film. Its excellent physical and chemical performance indicators, convenient construction technology, integrity of the waterproof and anti-corrosion system, and environmental protection are beyond the reach of any other traditional protective materials and technologies. It is widely used in water-proof, anti-corrosion and wear-resistant "two-proof and one-resistant" projects in urban subways, high-speed railways, tunnels and bridges, water conservancy, electromechanical, marine chemical, military and civilian projects.
