Abstract: Curable compositions comprising stable, water dispersible, curable polymers containing sterically hindered alkoxylated silane groups and acid groups blocked by fugitive bases at 0.1 to 75 weight percent of the total composition and water at 99.9 to 25 weight percent of the total composition are taught herein, as well as methods for the use and manufacture thereof. Additional components, such as emulsifiers, buffers and thickeners are also taught. These compositions are useful as adhesives, sealants and paints. The compositions have improved properties including solvent resistance, adhesion, hardness, abrasion resistance and mar resistance.

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.

These compositions are useful as adhesives, sealants and paints. The compositions have improved properties including solvent resistance, adhesion, hardness, abrasion resistance and mar resistance. Particular catalysts for use herein include dihydroxy bis ¢2hydroxypropanato (2-)-O1,O2! titanate mixed titanium ortho ester complexes, acetylacetonate chelate, bis(ethyl-3-oxobutanolato-O1,O3) bis(2-propanolato) titanium, alkanolamine complex of titanium and mercaptoalcohol, mercaptide or sulfide forms of diorganotins having either a Sn-S or Sn=S bond.

Abstract: The present invention teaches masonry water repellents comprising aqueous emulsions of alkylalkoxysilanes with either a quaternary ammonium surfactant or a mixture of a quaternary ammonium surfactant with an amino and/or a nonionic surfactant. The alkyl-alkoxysilane is present at a level of about one to sixty weight percent of the final solution weight. The surfactants are present at levels of about 0.05 to 25 weight percent of the final solution weight. The useful quaternary ammonium surfactants are quaternary ammonium modified dimethylpolysiloxanes. Amino and nonionic surfactants are used as additives to the quaternary surfactants. The types of nonionic surfactants contemplated herein are alkylamines and alkyl acetylenic alcohols.
