Abstract: A modified coating composition is disclosed. Said modified coating composition comprises a coating composition, a modifier, at least one dispersing agent, at least one solvent and at least one binder, wherein the coating composition, the modifier, the at least one dispersing agent, the at least one solvent and the binder are collectively ground to obtain nanoparticles of the modifier dispersed therein. The modifier, in accordance with the present invention, comprises of mixed oxide particles bonded to a silane crosslinking agent. Herein, the mixed oxide particles comprise alumina and silica in a weight ratio between 30:70 and 40:60.
