Abstract

An article having a metallic or ceramic surface, such as a watch case, or watch strap, has its surface protected by a clear glassy coating to prevent scratching or chemical damage, applied by coating the surface with an aqueous coating composition containing waterglass dissolved therein and silica sol dispersed therein in proportions such that the molar ratio of silica to sodium oxide i.e. SiO2/Na2O, in the coating composition is in the range from 4 to 10. This is followed by drying, preferably with heating to give a clear and hard glassy thin film on the surface which is remarkably resistant to water, sweat and scratch formation and is insusceptible to staining.
