    Abstract: An abrasion resistant and ultraviolet radiation resistant coating is disclosed comprising an inorganic oxide matrix formed by the hydrolysis and condensation of an alkoxysilane and/or other metal alkoxide, further comprising cerium oxide for ultraviolet radiation resistant and/or silica for improved abrasion resistance. A partially hydrolyzed silane sol containing colloidal cerium oxide is ion-exchange with an anion exchange resin in one embodiment. In another a partially hydrolyzed silane sol containing colloidal silica is ion-exchanged to remove sodium ions prior to adding the colloidal ceria resulting in improved properties in the coating composition and resultant coating.
