Abstract

The invention relates to special stable dispersions which crosslink at room temperature upon exposure to moisture in the atmosphere. The dispersions comprise polysiloxanes, vinyl-grafted polysiloxanes and condensation products, e.g. by weight approximately comprising PA1 I. 20-90% of at least one diorganopolysiloxane optionally terminated by OH, PA1 II. 5-85% of at least one aliphatic or mixed aliphatic/aromatic polycondensation product or polyaddition product, polyether, or vinyl polymer with a glass temperature T.sub.G of up to 40.degree. C. and/or a vinyl monomer-grafted derivative thereof, and PA1 III. 5-85% of at least one organopolysiloxane modified by grafting with at least one vinyl monomer and comprising PA2 (A) 10-90% of a diorganopolysiloxane optionally terminated by OH, PA2 (B) 10-90% of polymerized units of at least one vinyl compound, and PA2 (C) 0-80% of at least one aliphatic or mixed aliphatic/aromatic polycondensation product or polyaddition product, polyether, or vinyl polymer with a glass temperature T.sub.G of up to 40.degree. C.
