Abstract: A method of preparing a coating or a sealant wherein a class of epoxysilanes; optionally, an emulsifier; water; a polymer containing a functional group with an active hydrogen; and a curing catalyst are mixed together.

Abstract: The present invention provides stable epoxy silane solutions and emulsions and methods for the preparation of stable epoxy-silane solutions and emulsions comprising: (I) a water insoluble or slightly soluble epoxysilane; (II) optionally, an emulsifier; (III) water; (IV) a water dispersible polymer containing a functional group with an active hydrogen; and (V) a catalyst. Also provided are two part systems such that an epoxysilane solution or emulsion comprising components (I)-(III) are combined and the components (IV) and (V) may be added upon use of components (I) to (III). Moreover, additional components, such as pH buffers may be added. Said compositions may be used for, among other things, coatings, adhesives and sealants. The water epoxy functional silane for use herein are of the general structure R.sup.1.sub.a R.sup.2.sub.b Si(OR.sup.3).sub.4-a-b where R.sup.1 is an epoxy substituted alkyl or aralkyl group, where the alkyl may have from four to thirty carbon atoms, R.sup.

Abstract: A method for preparing chloroalkylalkoxysilanes by reacting an allylic chloride with a small molar excess of a hydromethoxysilane in the presence of a ruthenium catalyst and preferably in the substantial absence of an inert solvent.
