ABSTRACT:
The present invention relates to organosiloxane compositions that are reaction products of 1) a silane containing at least 3 hydrolyzable groups per molecule, 2) a monohydric or polyhydric alcohol containing at least one organofunctional group and 3) a polyhydric alcohol containing no organofunctional groups or ethylenic unsaturation, wherein said reaction products contain at least two silicon atoms. The organosiloxane compositions are particularly useful as adhesion promoting additives for curable organosiloxane compositions, particularly those that cure by a platinum group metal-catalyzed hydrosilation reaction.
