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—R; 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.

Coating composition

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 comprising: (a1) at least one polyaspartic ester, and (a2) optionally a polyetheraspartic ester; (b) an isocyanate component comprising: (b1) at least one isocyanate prepolymer having an isocyanate group equivalent of 300 to 1100, 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 from 1:4 to 4:1; (c) a catalyst; and (d) optionally an additive; wherein the coating composition has a molar ratio of isocyanate groups to isocyanate-reactive groups of 1.5:1 to 8:1. The coating composition provided by the present invention has a long pot life, and the resulting coating has the advantages of fast drying and high hardness.

Disclosed are seed treatment compositions that include: (a) an aqueous polyurethane dispersion; and (b) an insecticide, a fungicide, a nematicide, and/or other pesticides. Also disclosed are seeds treated with such a treatment compositions and methods for treating a seed using such treatment composition.
