Process for reticulating organopolysiloxane compositions free from Si-H bonds and ethylenically unsaturated activated radicals

摘要

An organopolysiloxane composition is facilely photocured, e.g., into a variety of non-stick coatings, by subjecting to a photocross-linking amount of ultraviolet irradiation, admixture of (i) a polysiloxane comprised of hydroxysilyl groups devoid of Si-H bonds and containing no organic radicals which include sites of activated ethylenic unsaturation, and (ii) an aminopolyalkoxysilane.
