Abstract
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 the group consisting of (i) epoxy-substituted 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.
