Abstract: Disclosed is a coating composition for wet coating to block ultraviolet light radiation as being applied on a vehicle glass. The composition comprises: a binder including an amount of about 15 to 20% by weight of tetraethoxysilane (TEOS) and an amount of about 10 to 15% by weight of glycidoxypropyltrimethoxysilane (GPTS), an amount of about 20 to 35% by weight of an organic solvent, an amount of about 0.5 to 2% by weight of a curing agent, an amount of about 0.1 to 0.5% by weight of a leveling agent, an amount of about 10 to 40% by weight of a hydrophobically surface-treated inorganic nanosol, an amount of about 8 to 12% by weight of an inorganic ultraviolet blocking agent and an amount of about 1 to 3% by weight of a fluorescent whitening agent, all these % by weights based on the total weight of the coating composition. Accordingly, the coating composition may be used as a vehicle glass coating agent due to substantially improved abrasion resistance and durability.
