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: Curable composition comprising a stable, water dispersible, curable polymer containing a sterically hindered alkoxylated silane group at 0.1 to 75 weight percent of the total composition; a water dispersible or water soluble, hydrolytically stable organometallic catalyst, at 0.1 to 10 weight percent of the total composition; and water at 99.8 to 24.9 weight percent of the total composition are taught herein. 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 [2-hydroxypropanato (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 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.
