AQUEOUS CURABLE ALKOXY SILANE/ALKOXY SILYLATED POLYMER COMPOSITIONS WITH EXTENDED SHELF LIFE

摘要

The present invention provides stable alkoxy silane containing compositions and methods for the preparation of a stable silane containing composition 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 compone nt (IV) may be added upon use of components (I) to (III). Moreover, additional components (V) such as catalysts and pH buffers may be added. The compositions of the present invention are stable for at least about three to twelve months.
