Title:
LIGHTFAST EPOXY RESIN
Document Type and Number:
WIPO Patent Application WO2003016377
Kind Code:
A9
Abstract:
A lightfast epoxy resin is formed by phosgenating Bisphenol A by reaction with phosgene to produce Bisphenol A bischloroformate. The Bisphenol A bischloroformate is then reacted with either epichlorohxdrin, glycidol or pinacol and another chemical to produce a lightfast epoxy resin. By phosgenating the Bisphenol A prior to the reaction with either epichlorohydrin, glycidol or pinacol and another chemical, the resulting epoxy resin has improved lightfastness and is not degraded by sunlight. The epoxy resin of the present invention can be used us paints, coatings, and plastics for vehicles.
