Spray polyurea waterproof anticorrosive paint

This product is A kind of A, B two-component, solven-free, fast curing green environmental protection elastic waterproof material, according to different film reaction groups and divided into high elastic spraying (pure) polyurea waterproof coating (JNC) and high elastic spraying polyurethane (urea)(commonly known as semi-polyurea) elastic waterproof coating (JNJ), according to physical properties are divided into type I and type II. The A and B components are mixed and sprayed in the spray gun of the special spraying equipment, and the elastomer waterproof film is formed by rapid reaction and solidification.
The A component of high elastic spraying (pure) polyurea waterproof coating is a semi-prepolymer prepared by the reaction of hydroxyl terminal compound with isocyanate. The B component is a mixture of terminal amino resin and terminal amino chain extender and must not contain any hydroxyl components and catalysts, but is allowed to contain a small amount of pigment and dispersing additives.
The A component of elastomeric spray polyurethane (urea) elastic waterproof coating is a semi-prepolymer prepared by the reaction of hydroxyl terminal compound with isocyanate. B component is a mixture of hydroxy-terminated resin or amino resin and amino chain extender. In B component, a catalyst for improving reaction activity can be contained, allowing a small amount of pigment and dispersing additives.
This product needs to be sprayed by special professional construction machinery when forming film. Its excellent physical and chemical properties, convenient construction technology, integrity of 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 urban subway, high-speed railway, tunnel bridge, hydraulic machinery, Marine chemical industry, military and civilian dual-use projects of waterproof, anti-corrosion, wear-resistant "two prevention and one resistance" project.
