Safety And Environmentally Spraying Polyurea SPUA-90 AB Courts Sports Surface Flooring Athletic Running Track
Special polymer material with unmatched weather resistance, high impact resistance, pressure resistance, heavy load (strength of 425 cement), high tensile strength, elongation at break, in use and construction In the process, it can achieve fast, convenient, safe and environmentally friendly performance. It is a kind of material that can be widely used in various kinds of stadiums, fitness paths, roller skating venues, kindergartens, schools and other places.
It is an elastomeric substance formed by the reaction of an isocyanate component (referred to as component A) with an amino compound component (abbreviated as component R). The isocyanate may be either aromatic or aliphatic. The component A thereof may be a monomer, a polymer, a derivative of an isocyanate, a prepolymer, and a semi-prepolymer. Prepolymers and semi-prepolymers are prepared by reacting a terminal amino group or a terminal hydroxyl compound with an isocyanate. The R component must be composed of a terminal amino resin and a terminal amino chain extender. The terminal amino resin must not contain any hydroxyl component and catalyst, but may contain an auxiliary agent for facilitating pigment dispersion.
