Abstract
Mixtures of silicone resin with an organopolysiloxane copolymer prepared by hydrosilylating a substantially linear polymer containing an isocyanate reactive group with an Si—H containing organopolysiloxane, and reacting this intermediate with a diisocyanate, are useful as long lasting defoamers which are compatible with numerous media.
