Epoxy-silicone compositions.

摘要

Epoxysilicones, epoxyfluorosilicones , and organic cycloaliphatic epoxy resins are blended with fluoro-containing organic molecules and an iodonium photocatalyst to form a UV-curable composition which exhibits improved adhesion resistance and solvent resistant properties upon curing when compared to similar compositions without the fluoro-organic molecule. The co-curable compositions can be cured at very high conveyor speed rates, such as 500 fpm. The curing also requires much less UV energy than is necessary to cure similar compositions without the fluoro-organic molecule. By selecting proper fluoro-organic molecules, the fluorine content of the composition can be greatly increased.
