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 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. The compositions of the present invention are stable for at least about three to twelve months.
L'invention concerne des compositions stables contenant de l'alcoxysilane et des procédés de préparation d'une composition stable contenant du silane, qui comprend: (I) de l'alcoxysilane insoluble ou légèrement soluble dans l'eau; (II) un émulsifiant; (III) de l'eau; et (IV) un polymère dispersible ou émulsionné dans l'eau contenant un groupe fonctionnel alcoxysilane. L'invention concerne également deux systèmes partiels constituant une émulsion d'alcoxysilane dans laquelle les constituants (I)-(III) sont combinés et où l'on peut ajouter le composant (IV) après utilisation des constituants (I) à (III). On peut également ajouter des constituants (V) supplémentaires tels que des catalyseurs et des tampons de pH. Les compositions conformes à la présente invention sont stables pour au moins trois à douze mois environ.
