Beschreibung
Zusammenfassung:	Adhesion promoting additives for organosiloxane compositions that cure by a platinum-catalyzed hydrosilation reaction are reaction products of (1) an ethylenically unsaturated ether of a polyfunctional alcohol and (2) at least one silicon compound selected from (i) epoxysubstituted organosilicon compounds containing at least one hydrolyzable group per molecule and (ii) tetraalkyl orthosilicates, also referred to tetraalkoxysilanes, where the reaction is conducted in the presence of a suitable catalyst such as an organotitanium compound. The additive optionally includes a chelated organoaluminum compound.
