PRECISION OF DISCLOSURE: The subject of the invention is organic compositions. polysiloxane, solvent-free, comprising a polydiorgano-polysiloxane with hydroxysilyl group, a polyorganosilo-branched xane, with hydroxysilyl group, a crosslinking agent, with polyalkoxysilyl group, and a catalyst. These components sitions which are characterized in that the catalyst is a organic iron or zirconium derivative, soluble in organopolysiloxane medium, can be used for coating or impregnation, and allow materials to be obtained with good non-stick properties, as well as seals with good water-repellent properties and good resistance to sol-touts. |
