The present disclosure relates to a protective coating composition for a hard surface, wherein the composition comprises an organic solvent and a polysiloxane having the general formula (I), wherein: R, R, R, R, R, R, Rand Rare independently an alkyl group having from 1 to 8 carbon atoms; Y and Z are independently a divalent linking group selected from the group consisting of urea, urethane, oxygen atom, sulfur atom and alkylene having from 1 to 8 carbon atoms; A, B, L and M are independently a divalent slinking group selected from the group consisting of alkylene having from 1 to 8 carbon atoms, with the proviso that if the combined linking groups formed by -A-Y-L- and -M-Z—B— are independently an alkylene, then the alkylene is independently different from ethylene; n is an integer from 5 to 1500; and m and p are independently an integer from 1 to 3. In another aspect, the present disclosure is directed to a method of reducing contamination from a hard surface.

Polysiloxane-based protective coating composition for hard surfaces

A composition that includes an amino-functional compound having at least one silane group, a fluorinated compound represented by formula Rf{&#x2014;X&#x2014;[Si(Y)(R)]}, and a non-fluorinated organic solvent having a flashpoint of at least 40&#xb0; C. A method of making a treated article having a metal surface using a composition that includes an amino-functional compound having at least one silane group, a fluorinated compound represented by formula Rf{&#x2014;X&#x2014;[Si(Y)(R)]}, and an organic solvent having a flashpoint of at least 40&#xb0; C. is also disclosed. Another method includes treating the metal surface with a primer composition including an amino-functional compound having at least one silane group to provide a primed metal surface and subsequently treating the primed metal surface with a treatment composition including a fluorinated compound represented by formula Rf{&#x2014;X&#x2014;[Si(Y)(R)]}. The compositions each include up to one percent by weight of an organic solvent having a flashpoint up to 40&#xb0; C.

Composition including silanes and methods of making a treated article

A polymer is provided comprising a first pendant group selected from at least one of a perfluorinated ether group or a perfluoroalkanesulfonamido group, a second pendant group comprising an ammonium group, wherein the second pendant group is free of silicon, and a third pendant group comprising an ammonium group and a reactive silicon-containing group. A composition comprising the polymer is provided. The polymer and composition are useful for protecting a substrate, for example, to render the substrate oil repellent, water repellent, or both, or to provide stain repellency to the substrate.
