haerdning av epoxisiloxan foer katalytiska acceleratorer och katalyter foer katjoniskt uv haerdningssystem.

摘要

Photopolymerizable coating compositions are described which comprise an organic cycloaliphatic polyepoxide in admixture with a cure accelerating amount of a low molecular weight alpha, omega-cycloaliphatic epoxy-functional siloxane which, when photocured using an onium salt photoinitiator, require less energy to cure, and thus coatings utilizing these compositions may be cured more rapidly under the same conditions than can compositions containing only the organic cycloaliphatic polyepoxide.
