To understand the polyurethane waterproof coating on the polyurethane screen, we must first look at the waterproof material. The earliest waterproof materials were asphalt and petroleum green paper linoleum. It was born in Europe and introduced to China in the 1920s. With the advancement of science and technology, modern waterproof materials have developed rapidly. In the 1980s, various polymer waterproof materials were introduced one after another.

Polyurethane waterproof coating is a polyurethane waterproof coating made of addition polymerization of isocyanate, polyether and catalyst, anhydrous additives, anhydrous fillers, solvents, etc., and is made through mixing and other processes. This kind of coating is a moisture-curing coating with the characteristics of high strength, high elongation, excellent water resistance, and strong adaptability to base deformation.

Polyurethane waterproof coating is an environmentally friendly waterproof coating with a single-component liquid structure. It is based on imported polyurethane prepolymer and does not contain additives such as tar or asphalt. It cures when exposed to moisture in the air to form a strong, durable, seamless monolithic film on the surface of the substrate.

Therefore, the “Polyurethane Screen” made of polyurethane raw materials has excellent waterproof and oil resistance properties, and has excellent performance in the screening process using water and oil as media.
