Abstract: The present invention relates to a process for providing a low-chloride hydrolyzate comprising subjecting an acid or base hydrolyzed substrate of a chlorosilane direct process residue to a mechanochemical means to provide a hydrolyzate with a chloride content of less than about 1.1% by weight. The process of present invention is especially useful in cement kilns and smelter operation.

Abstract: The present invention relates to a process for providing a low-chloride hydrolyzate comprising contacting an acid or base hydrolyzed substrate of a chlorosilane direct process residue with nitric acid to provide a hydrolyzate with a chloride content of less than about 1.8% by weight. The process of present invention is especially useful in cement kilns and smelter operation.

Abstract: The invention relates to branched polysiloxane compositions resulting from copolymerizing under hydrosilylation conditions a component mixture comprising (a) one or more organosilicon compounds containing at least two unsaturated hydrocarbon functional groups per molecule, and (b) one or more silylhydride-containing compounds containing at least two silylhydride functional groups per molecule, with the provision that (i) at least one component (a) or (b) contains at least three functional groups per molecule; (ii) a component (a) or (b) having a higher number of functional groups per molecule is present in a molar amount equal to or lower than a molar amount of the other component (a) or (b) having a lower number of functional groups per molecule; and (iii) unsaturated hydrocarbon compounds are excluded from the component mixture.

Abstract: The invention relates to coating formulations comprising (i) a silicone-based coating component susceptible to misting under mist-producing conditions; and (ii) an anti-misting amount of a branched polysiloxane component resulting from copolymerizing under hydrosilylation conditions a component mixture comprising (a) one or more organosilicon compounds containing at least two unsaturated hydrocarbon functional groups per molecule, and (b) one or more silylhydride-containing compounds containing at least two silylhydride functional groups per molecule, with the provision that (i) at least one component (a) or (b) contains at least three functional groups per molecule; (ii) a component (a) or (b) having a higher number of functional groups per molecule is present in a molar amount equal to or lower than a molar amount of the other component (a) or (b) having a lower number of functional groups per molecule; and (iii) unsaturated hydrocarbon compounds are excluded from the component mixture.

Abstract: The invention relates to compositions comprising (I) a silicone-based coating component susceptible to misting under mist-producing conditions; and (II) an anti-misting amount of at least one branched polysiloxane of reduced molecular weight and viscosity. The invention also relates to a process for coating a substrate with the above coating formulation, as well as hardened silicone-based coatings or films produced by subjecting the coated substrate to one or more curing steps.

Abstract: The invention relates to a branched polysiloxane composition of reduced molecular weight and viscosity of particular use as mist suppressants in silicone-based paper release coatings. The invention also relates to methods for producing these branched polysiloxane compositions of reduced viscosity.
