Abstract
The present invention provides stable epoxy silane emulsions and methods for the preparation of such compositions comprising (I) a water insoluble or slightly soluble epoxysilane; (II) an emulsifier; (III) water; and (IV) a water dispersible polymer containing a functional group with an active hydrogen. Also provided are two part systems such that an epoxysilane emulsion comprising components (I)-(III) are combined and the component (IV) may be added upon use of components (I)-(III). Moreover, additional components (V), such as catalysts and pH buffers, may be added. Such compositions may be used for, among other things, coatings, adhesives and sealants.
