Patent ID: 7211330

Claim:
Polyorganosiloxane composition obtained by mixing together the following components; a) at least one crosslinkable polyorganosiloxane; b) at least one alkoxysilane/siloxane agent; a) at least one phosphoric acid ester of the formula: O═P(OR 17 ) 3-p (OH) p where p=1 or 2 and R 17 is selected from the group consisting of linear or branched and optionally substituted C 1 –C 30 alkyl groups, linear or branched C5–C 14 cycloalkyl groups, C 6 –C 14 aryl groups, C 6 –C 31 alkylaryl groups, linear or branched C 2 –C 30 alkenyl groups or linear or branched C 1 –C 30 alkoxy(C 1 –C 30 )alkyl groups, polyalkenyloxy groups (polyethers), triorganyl-silyl and diorganyl (C 1 –C 30 )alkoxysilyl groups and/or a salt thereof; d) at least one catalyst containing tin or at least one catalyst containing a titanium chelate; e) at least one aminoalkylsiloxane; f) 0.05 to 2 wt % based on the weight of the composition of at least one compound selected from the group consisting of an isocyanurate of the formula: where R 22 , R 23 and R 24 may be the same or different and each is selected independently of the others from the group consisting of trisalkoxysilylalkyl and alkenyl with the provision that at least one of the substituents R 22 , R 23 and R 24 is a trisalkoxysilylalkyl group, a cyanurate of the formula: where R 25 , R 26 and R 27 may be the same or different and each is selected independently of the others from the group consisting of trisaikoxysilylalkyl and alkenyl with the provision that at least one at the substituents R 25 , R 26 and R 27 is a trisalkoxysilylalkyl group, condensation products having Si—O—Si bonds of said cyanurates and isocyanurates, and mixtures thereof; g) optionally a filler; h) optionally an additive selected from non-crosslinkable siloxanes, adhesion promoters, fungicides, solvents, organic dyes, pigments and combinations thereof.
