<p>The invention is concerned with a composition for coating a substrate such as glass to provide a UV protective coating. The composition includes a major portion of a base carrier material and a minor portion of an inorganic oxide material selected from the group consisting of zinc oxide, cerium oxide and titanium dioxide. The minor portion of inorganic oxide material is dispersed in the major portion of the base carrier material as a particulate dispersion to thereby create a coating capable of absorbing UV light and transmitting visible light. In particular the invention takes advantage of the fact that some UV adsorbing inorganic oxides can be milled to a sub micron particle size at which point they become transparent/translucent in dispersion. A transparent UV coating can therefore be made.</p> |
