Abstract
Abstract A 1 to 8 micron organic/inorganic (epoxy/glass) wear surface coating over a clear, protective layer provides excellent stain and gloss protection. An acid hydrolyzed silicate is combined with an acid hydrolyzed silicone coupling agent; an epoxy monomer; a photoinitiator and silicon oil surfactant to produce a coating composition which is dried to remove alcohol/water solvent and U.V. cured.
