Abstract
Stable alkoxy silane containing compositions and methods for the preparation of a stable silane containing compositions comprising: (I) a water insoluble or slightly soluble alkoxy silane; (II) emulsifier; (III) water; and (IV) water dispersible or emulsified polymer containing an alkoxy silane functional group. Also provided are two part systems such that an alkoxy silane emulsion comprising components (I)-(III) are combined and the component (IV) may be added upon use of components (I) to (III). Moreover, additional components, (V), such as catalysts and pH buffers may be added.
Claims34
A composition comprising:
- (I) about 0.1 to 20 weight percent of a water insoluble or slightly soluble, saturated alkoxy silane;
- (II) about 0.05 to 30 weight percent of an emulsifier;
- (III) about 30 to 99 weight percent of water;
- and (IV) about 0.1 to 70 weight percent of a water dispersible or emulsified polymer containing an alkoxy silane functional group, provided that said polymer contains one or more carbon atoms and said alkoxy silane functional group is bound to the polymer through a Si--C bond;
- wherein said composition is shelf stable.
A method for the preparation of a shelf stable composition comprising;
- (a) dispersing a water insoluble or slightly soluble alkoxy silane in an aqueous solution with emulsifier to yield an aqueous emulsion, and (b) adding the silane emulsion to a water dispersed or emulsified organic polymer which contains a silyl ester functional group, provided that said polymer contains one or more carbon atoms and said alkoxy silane functional group is bound to the polymer through a Si--C bond.
A composition comprising:
- (I) about 0.1 to 20 weight percent of a water insoluble or slightly soluble alkoxy silane with an unsaturated functionality thereon;
- (II) about 0.05 to 30 weight percent of an emulsifier;
- (III) about 30 to 99 weight percent of water;
- and (IV) about 0.1 to 70 weight percent of a water dispersible or emulsified polymer containing an alkoxy silane functional group where said alkoxy functional group is different than the silane of (I), provided that said polymer contains one or more carbon atoms and said alkoxy silane functional group is bound to the polymer through a Si--C bond;
- wherein said composition is shelf stable.
