Aminopropyl-functional siloxane oligomers

A composition comprising at least one organofluorine-functional silane and/or siloxane, at least one mineral acid and at least one metal salt of aluminum(III), tin(II), tin(IV), iron(III) or titanium(III); a process for preparing said composition and to its use; and surface-modified substrates obtainable by coating with said composition.

Fluoroalkyl-functional organopolysiloxane-containing compositions based on water, a process for their preparation and their use

Fluoroalkyl organosilicon compounds are prepared by reacting fluoroolefins with organosilicon compounds that contain at least one H-Si group, in the presence of a Pt(0) complex catalyst. Further, fluoroalkylalkoxy organosilicon compounds are prepared by esterifying fluoroalkyl organosilicon compounds. The process proceeds uniformly under mild conditions with high yields and selectivities.

Stable compositions of water-soluble amino-and alkenyl-functional organosiloxanes, process for their preparation and their use

An oligomerized polyorganosiloxane cocondensate which may be obtained, in part, by mixing an water-soluble amino-functional organosilane represented with at least one of the followoing: a fluoro-functional organosilane, an organosilane, and an organosilane. The cocondensate may be used, for example, in a method of treating surfaces.

Oligomerized organopolysiloxane cocondensate, its production and its use for treatment of surfaces

The present invention relates to surface-modified fillers obtained by mixing a filler with water, adding an water-based organosiloxane composition with very thorough mixing, wherein the organosiloxanes are soluble in water and contain, in addition to OH groups, at least one amino-functional group and optionally a functional group from the series consisting of alkyl, haloalkyl, alkenyl, glycidyl ether alkyl, acryloxyalkyl and methacryloxyalkyl, and wherein a functional group is bonded to each silicon atom of the organosiloxane, and drying the mixture. The present invention also provides a process for the surface modification of fillers, their use and ethylene-vinyl acetate copolymer compositions which include the surface-modified fillers.
