Abstract:
The present invention provides stable epoxy silane emulsions and methods for the preparation of a stable epoxy-silane emulsions 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) to (III). Moreover, additional components (V), such as catalysts and pH buffers may be added. Said compositions may be used for, among other things, coatings, adhesives and sealants. The water dispersible or slightly soluble epoxy functional silane for use herein are of the general structure R1aR2bSi(OR3)4-a-b where R1 is an epoxy substituted alkyl or aralkyl group, where the alkyl may have from four to thirty carbon atoms, R3 is an alkyl or alkoxy-substituted alkyl, aryl or aralkyl group having from two to ten carbon atoms, R2 is an alkyl group or alkoxy substituted alkyl, aryl or aralkyl group having from one to ten carbon atoms, a is one to three, and b is zero to two, with the proviso that a+b is 1, 2, or 3. R1, R2, and R3 group may be cyclic, branched or linear.
