A crosslinked polysiloxane dispersion comprising a product of a siloxane polymer or polymer mixture having a viscosity of greater than 5000 mPa.s but less than 500,000 mpa.s, and at least one self catalyzing crosslinker, a surfactant, and water.

Elastomers from silicone emulsions having self-catalytic crosslinkers

A crosslinked polysiloxane dispersion comprising a siloxane polymer, polymer mixture, or polymer/solvent mixture, capable of crosslinking via condensation, addition or free radical reactions, and having a viscosity of greater than 5000 mPa.s but less than 500,000 mPa.s, if required, 0.1 to 10 weight parts of a crosslinking agent, and, if required, depending on the nature of the catalyst and silicon cure system, 0.000001 to 10 weight parts of a catalyst, 0.5 to 10 weight parts of a surfactant or surfactant mixture, and 0.5 to 25 weight parts water per 100 weight parts siloxane polymer. Optionally, adhesion promoters, pigments, reinforcing or non-reinforcing fillers, silicone resins, stabilizers, freeze/thaw additives, etc. may also be added to the dispersion.

Shelf stable cross-linked emulsions with optimum consistency and

An aqueous silicone emulsion which upon the evaporation of the water forms a surface modified elastomeric silicone material providing improved coverage and adhesion of paint and reduced staining and coefficients of friction, each relative to other silicone elastomers from aqueous emulsions. The silicone emulsion comprises (A) water; (B) a plurality of particles dispersed in the water comprising a crosslinked product of a diorganosiloxane polymer; (C) a surfactant; and (D) an amount of an oxygen curing compound or a salt thereof effective for the surface modification. If a surface active salt of an oxygen curing compound is used, it may not be required to add additional surfactant in order to form the silicone emulsion.

Surface modified silicone elastomers from aqueous silicone emulsions

A crosslinked polysiloxane dispersion comprising a product of a siloxane polymer or polymer mixture having a viscosity of greater than 5000 mPa.s but less than 500,000 mPa.s, and at least one self catalyzing crosslinker, a surfactant, and water.

A method of producing alkoxysilethylene endblocked polydiorganosiloxane consists essentially of first reacting hydroxyl endblocked polydiorganosiloxane with an excess of a SiH compound having from 2 to 4 SiH groups in the presence of a platinum catalyst, then reacting that product with vinyltrialkoxysilane to give the desired polymer.
