Abstract: PURPOSE: The coating composition prepared by adding dicyandiamide as a curing catalyst to a silicon-based coating composition comprising a silanol partial condensate and a colloidal silica dispersion is provided, which has excellent abrasion resistance and adhesion property and can store at ordinary temperatures and is excellent in low temperatures cross-linking curing and simplifies coating processes without changing mechanical and mechanical properties. CONSTITUTION: In a silicon-based coating composition comprising a silanol partial condensate and a colloidal silica dispersion, the composition contains a silanol partial condensate having a particle diameter of 2 to 30 micrometer and a colloidal silica dispersion in a weight ratio of 30 to 80 and 20 to 70% by weight and 0.05 to 2.5% by weight of dicyandiamide as a curing catalyst based on the solids content of the mixtures. The composition is suitable for coating an automobile part, optical material, building material and electrical material.
