One-component, solvent-free organosiloxane composition comprising
a) a linear or branched polyorganosiloxane containing at least two alkenyl or alkynyl groups, as component A;b) a linear or branched polyorganosiloxane containing at least 3 Si—H groups, as component B;c) a hydrosilylation catalyst as component C;d) an alkynol of the general formula (I);whereinR1, R2, R3 are selected independently of one another from H, C1-C6-alkyl and substituted or unsubstituted C3-C6-alkyl; orR1 is selected from H, C1-C6-alkyl and substituted or unsubstituted C3-C6-cycloalkyl, and R2, R3 are bonded together and form a 3- to 8-membered ring which can be substituted by one or more C1-C3-alkyl groups, as component D; ande) a fumed silica as component E. |
