Study on Unsaturated Polyester/Polyurethane Two Component Coating

This paper presents the preparation of two component coating which is synthesized by unsaturated polyester resin end blocked by hydroxy and prepolyurethane end blocked by isocyanate. It is a fine decorative coating with high lustre, high fullness and can cure at ambient temperature. Molecule structure of unsaturated polyester is designed to control the whole properties of the coating. The step reation between hydroxy and isocyanate is not retarded by oxygen in the air, and the coating has good surface hardness. The cross linking system is also discussed.
