ABSTRACT:
Curable thermosetting resin compositions comprise a continuous phase of a curable thermosetting organic or a curable thermosetting silicone resin containing dispersed finely divided particles of a cured composition prepared by reacting 1) an organopolysiloxane, 2) a curing agent for the organopolysiloxane, 3) an alkoxy group-containing organosilicon compound and 4) a compound of aluminum or zirconium where this compound is an alkoxide, phenoxide, carboxylate or a derivative of a beta- dicarbonyl compound or o-hydroxyketone. Ingredients 3) and 4) can be prereacted and the cured composition optionally contains a filler. The presence of ingredients 3) and 4) imparts improved adhesion between the continuous an dispersed phases of the composition.
