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.
