Abstract
Composite coating on aluminum article comprising base layer formed from alkali metal silicate compound and outer layer formed of a dispersion of colloidal silica and a silicone resin is tightly adherent to the aluminum surface, provides protection from corrosion and is abrasion resistant. Improved aluminum reflectors are made by suitably brightening the surface to provide a highly specular reflective surface, applying a base coating of a silicate solution on the thus treated surface, heating the thus applied base coating to remove the chemically bound water therefrom, rinsing the base coating to remove alkali metal ions therefrom, applying an outer coating of the colloidal-silica-silicone resin composition, and drying the latter coating.
