What Is Polyurea ?
Polyurea is an elastomer formed by the reaction of isocyanate component and synthetic resin blend component. Isocyanates may be aromatic or aliphatic. It may be a monomer, polymer, or prepolymer. Prepolymers or semi-prepolymers may be made from either amine-terminated polymer resins or hydroxy-terminated polymer resins.
At present, according to different construction methods on the market, polyurea can be divided into spray polyurea and manual polyurea.
