In a polysiloxane molding composition which in the presence of water crosslinks to an elastomer and which comprises n (A) an α,ω-dihydroxyorganopolysiloxane with a viscosity of about 500 to 2,000,000 cP, n (B) a crosslinking agent, and n (C) a reinforcing filler, n the improvement which comprises including therein in about 0.1 to 10% by weight a silicon compound containing at least 3 alkoxy groups and preferably of the formula n n R.sub.n Si(Alkoxy).sub.4-n n n in which n R is alkyl with 1 to 10 carbon atoms, n Alkoxy has 1 to 4 carbon atoms, and n n is 0 or 1, n whereby the elastomer ultimately produced exhibits improved direct adhesion to various substrates. |
