ABSTRACT:
A self-emulsifying, liquid treatment composition comprises the polysiloxane reaction product of (a) at least one alkoxysilane, alkoxysiloxane, or siloxane compound comprising at least one hydrophobic moiety selected from the group consisting of alkyl, aryl, aralkyl, and alkaryl moieties; (b) at least one alkoxysilane, alkoxysiloxane, or siloxane compound comprising at least one hydrophilic moiety selected from the group consisting of protonated and unprotonated azaalkyl and silyl-containing azaalkyl moieties; and (c) at least one fluorine-containing alkoxysilane compound which is capable of reaction with component (a) and/or component (b) and which comprises at least one perfluoroalkyl group having at least four carbon atoms and optionally containing one or more catenary ether oxygen atoms. The composition can be used to render substrates, especially porous substrates (e.g., concrete, wood, or masonry), both water- and oil-repellent.
