Abstract:
A curable organosiloxane composition consisting essentially of:A. a first polyorganosiloxane having terminal siloxane units of the formula R.sup.1 R.sup.2.sub.2 SiO.sub.1/2 and non-terminal organosiloxane units of the formula R.sup.2.sub.2 SiO where R.sup.1 represents an alkenyl radical, and each R.sup.2 is independently selected from R.sup.1 or unsubstituted or substituted monovalent hydrocarbon radicals free of ethylenic unsaturation;B. a polyorganosiloxane cross-linking agent containing an average of at least two silicon-bonded hydrogen atoms per molecule, where the remaining silicon-bonded organic groups are monovalent hydrocarbon radicals selected from the same group as R.sup.2 ;C. an amount of a hydrosilation catalyst sufficient to promote curing of said composition; andD. a non-functional silicone fluid which is at least 25% by weight of said compositionwherein said composition forms a gel when cured.
