  • Foam control composition
    Patent number: 11597802
    Abstract: Foam control compositions along with formulations thereof and their use in various applications, including a method for making a foam control composition comprising a cross-linked polyorganosiloxane material including a dispersed silica filler, including the steps of: A) preparing a hydrosilylation reaction mixture by combining the following components: (i) silica filler, (ii) a polyorganosiloxane having at least two reactive substituents capable of addition reaction with component (iii) via hydrosilylation, (iii) a polyorganosiloxane having at least three reactive substituents capable of addition reaction with component (ii) via hydrosilylation, and (iv) a hydrosilylation catalyst; B) conducting a hydrosilylation reaction of components (ii) and (iii) until the reaction mixture at least partially gels to form a hydrosilylation reaction product; C) shearing the hydrosilylation reaction product of step B); and D) combining the hydrosilylation reaction product of step C) with a (v) silicone resin and an (vi)
