The present invention relates to a coating composition, a coating method and use of the composition, and a product coated with the coating composition. The coating composition comprises: (a) an isocyanate-reactive component; (b) an isocyanate component comprising: (b1) at least one isocyanate prepolymer, the isocyanate prepolymer being a reaction product of components comprising at least one aliphatic isocyanate and at least one polyether polyol, the polyether polyol having a weight-average molecular weight of 400 to 6000 and the structure of HO—R 1 n —R 2 ; and (b2) at least one isocyanate oligomer containing not less than two isocyanate groups, the weight ratio of the isocyanate prepolymer (b1) to the isocyanate oligomer (b2) being greater than 1:4 and less than 4:1; and (c) a catalyst; wherein the molar ratio of the isocyanate groups to the isocyanate-reactive groups in the coating composition is from 1.5:1 to 4:1. |
