Abstract
In a storable plastic organopolysiloxane composition which can be converted into a rubbery-elastic mass under the action of water and prepared by mixing an .alpha.,.omega.-dihydroxypolydiorganosiloxane with a silicon-containing crosslinking agent, the improvement which comprises incorporating in said mixture about 1 to 20% by weight of at least one material selected from the group consisting of dioxane, acrylonitrile, acetonitrile, trichloroethylene, butanesultone, butyl acetate and carbon tetrachloride. There may be included up to about 70% by weight of .alpha.,.omega.-bis-(triorganosiloxy)-polydiorganosiloxane, up to about 5% by weight of at least one heavy metal salt or amine as a crosslinking accelerant, and about 10 to 70% by weight of at least one inert filler.
