METODO PER RIDURRE LA VISCOSITA' SUPERFICIALE DI DISTRIBUZZIONI DI GEL E GRASSI DI ORGANOPOLISILOSSANO

The surface tack of a silicone gel or grease which is adheringly disposed on a substrate is decreased by coating the surface of the disposed gel or grease with a U.V.-curable organopolysiloxane liquid composition and exposing the coating to ultraviolet light until it is converted to a solid, non-tac...

Zusammenfassung:	The surface tack of a silicone gel or grease which is adheringly disposed on a substrate is decreased by coating the surface of the disposed gel or grease with a U.V.-curable organopolysiloxane liquid composition and exposing the coating to ultraviolet light until it is converted to a solid, non-tacky state. The U.V.-curable organopolysiloxane liquid composition comprises a curable mixture of an organopolysiloxane bearing olefinic radicals and an organopolysiloxane bearing silicon-bonded hydrogen radicals and/or silicon-bonded mercaptoalkyl radicals. The cured organopolysiloxane coating is easily penetrated, if desired, to provide access to the tacky silicone.
