PRODUCT DESCRIPTION  
This product is an environmentally friendly elastic waterproof material with dual components A and B, solvent-free, and fast curing. It is divided into high elasticity spray (pure) polyurea waterproof coating (JNC) and high elasticity spray polyurethane (urea) (commonly known as semi polyurea) elastic waterproof coating (JNJ) based on different film-forming reaction groups. It is classified into type I and type II according to physical properties. A. The B component is mixed and sprayed in the spray gun of the dedicated spraying equipment, and quickly reacts and solidifies to form an elastic waterproof film.
High elasticity spray (pure) polyurea waterproof coating component A is a semi prepolymer prepared by reacting terminal hydroxyl compounds with isocyanates; B component is a mixture composed of terminal amino resin and terminal amino chain extender, and must not contain any hydroxyl components or catalysts, but is allowed to contain a small amount of pigments and dispersed additives. High elasticity spray polyurethane (urea) (commonly known as semi polyurea) elastic waterproof coating component A is a semi prepolymer prepared by reacting terminal hydroxyl compounds with isocyanates; Component B is a mixture of terminal hydroxyl resin or terminal amino resin and terminal amino chain extender. It may contain catalysts to enhance reaction activity, and may contain small amounts of pigments and dispersed additives.
This product requires the use of special professional construction machinery for spray molding during film formation. Its excellent physical and chemical performance indicators, convenient construction process, overall waterproof and anti-corrosion system, and environmental friendliness are unmatched by any other traditional protective material and technology. It is widely used in waterproof, anti-corrosion, and wear-resistant "two prevention and one resistance" projects for urban subways, high-speed railways, tunnel bridges, water conservancy electromechanical, marine chemical, and military civilian dual-use projects.

SCOPE OF APPLICATION 
Suitable for the "two protections and one resistance" (waterproof, anti-corrosion, wear-resistant) sub projects of concrete surfaces, metal tanks, and internal and external surfaces of pipelines in engineering projects, it has been widely used in engineering fields such as urban subways, high-speed railways, tunnels and bridges, water conservancy and electromechanical engineering, petrochemicals, marine drilling, military civilian dual-use, etc.
