Abstract
A crosslinkable silicone composition including: a. at least one condensation-crosslinkable polydiorganosiloxane P having silanol, alkoxysilyl, carboxysilyl, ketoximinosilyl, amidosilyl and/or aminosilyl end groups; b. at least one silane or siloxane crosslinker V for the condensation-crosslinkable polydiorganosiloxane; c. at least one crosslinking catalyst K1 of the general formula (I) d. at least one adhesion promoter H of the general formula (IV). Compositions of this kind are especially suitable as adhesives, sealants, coatings or casting compounds and are notable for a low tendency to separate and very good adhesion under moist and warm conditions.
