Abstract

The present invention provides novel curable organopolysiloxane composition comprising at least about 50% by weight of a general organopolysiloxane having no more than two vinyl groups and up to about 50% by weight of a crosslink additive which is a polysiloxane having at least three vinyl groups and is copolymerizable with the organopolysiloxane. This curable composition when cured by heat, chemical or, preferably, radiation curing techniques produces crosslinked polysiloxane materials having unique combinations of cone penetration, elongation and tensile strength properties. A preferred use for these materials is as a sealant.
