The present invention provides for a composition comprising a silane having the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>(R<SUP>1</SUP>)(R<SUP>2</SUP>)(R<SUP>3</SUP>)Si-R<SUP>4</SUP>-Si(R<SUP>5</SUP>)(R<SUP>6</SUP>)(R<SUP>7</SUP>)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3</SUP>, R<SUP>5</SUP>, and R<SUP>6 </SUP>are each independently selected from the group consisting of 1 to 6 monovalent hydrocarbon radicals, aryl, and a hydrocarbon group of 7 to 10 carbons containing an aryl group; R<SUP>4 </SUP>is a hydrocarbon group of 1 to 3 carbons; R<SUP>7 </SUP>comprises an anionic, cationic or zwitterionic substituent. The silanes of the present invention exhibit resistance to hydrolysis over a wide pH range.
