Coating composition

Abstract

A coating composition having (A) an alcohol dispersion which includes silica having the hydrophobic surface and dispersed in an alcohol dispersion medium, the content of silica in a solid substance being 80% by weight or more; (B) a solution including a silicone oligomer which is obtained by a reaction of an alkoxysilane with water and has an average structural unit represented by R1nSiOx/2(OH)y (OR2)z (R1 representing an alkyl group, phenyl group or vinyl group, R2 representing an alkyl group and n, x, y and z representing numbers satisfying relations: 0.8≦n≦1.7, 2<x<3.2, y>0, z>0 and y+z=4−n−x); and (C) a curing agent. The coating composition exhibits excellent storage stability after the curing agent is added, suppresses aggregation of fine silica particles in spray coating and provides coating films having a high hardness and exhibiting excellent weatherability, water resistance, chemical resistance and adhesion.
