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.

Abstract: A two-component silicone composition made of a component A including a hydroxyl-group terminated polydiorganosiloxane P; between 0.05-5.0 wt. % water, relative to component A; and component B including a non-condensable polydiorganosiloxane; a catalyst K cross-linking polydiorganosiloxanes; between 0-50 wt. % of a first organosilane V1 according to formula (I), between 2-60 wt. % of a second organosilane V2 according to formula (II), up to 25 wt. % of organosilanes V3 having hydrolyzable alkoxysilane groups Si—ORa not falling under the formulae (I) and (II), with Ra being a hydrogen atom or monovalent, linear or branched alkyl group with 1-6 carbon atoms, Rb being a divalent, linear or branched alkyl group or alkenyl group with 2-20 carbon atoms, and Rc being a divalent, linear or branched alkyl group with 2-20 carbon atoms containing a secondary amino group; the composition containing less than 10 mole-%, relative to the amount of organosilane V2, of organosilanes with epoxy groups.
