The present invention is a composition of (a) a coating base selected from a water-dispersed coating, an epoxy polymer coating, an alkyd coating, a Type I urethane coating, or an unsaturated polyester coating; and (b) a fluorinated ester compound having a plurality of fluoroalkyl thioether groups, wherein the number average molecular weight of the fluorinated ester compound is &#x2264;30,000 Da; and where the fluorinated group Ris independently a straight or branched perfluoroalkyl group of 2 to 20 carbon atoms, which is optionally interrupted by one or more CH, CFH, ether oxygens &#x2014;O&#x2014;, or combinations thereof. The fluorinated ester compounds provide cleanability to the resulting coating made from the present composition.

Fluorinated ester compound additives for architectural coatings

The invention relates to a crosslinkable fluorinated urethane compound having at least one ethylenically unsaturated functional group. Such compounds are useful as coatings additives such that, when the coating is applied to a substrate, the additive compound is allowed to first migrate to the surface and subsequently crosslink to form a durable oil-, dirt-, and water-repellent surface.

Crosslinkable fluorinated urethane additives for durable exterior coatings

The present invention comprises a crosslinkable polymer compound comprising a fluorinated Unit A, an optional hydrophilic Unit B, an optional acidic or neutralized acid Unit C, a crosslinkable pendant olefin group-containing Unit D, and an optional hydrophobic alkyl Unit E. Such polymeric compounds are useful as coatings additives such that, when the coating is applied to a substrate, the additive compound is allowed to first migrate to the surface and subsequently crosslink to form a durable oil-, dirt-, and water-repellent surface.

Ethylenically crosslinkable fluorinated polymer additives for architectural coatings

The present invention comprises a composition and method of use for providing durable dirt pickup resistance to architectural coatings. Such compositions comprise a coating base and a post-modified crosslinkable fluoropolymer additive, such that the coatings additive is allowed to migrate to the coating surface and further cure once applied to a substrate. The compositions of the present invention provide durability to coating compositions, while also providing surface effects such as increased water and oil contact angles, enhanced dirt pickup resistance, and enhanced cleanability to the coating films.

Durable architectural coatings containing crosslinkable polymeric additives

The present invention comprises fluorinated ethoxylated polyurethanes of formula [R&#x2014;(X)&#x2014;(CHCHR&#x2014;O)&#x2014;CHCH&#x2014;O&#x2014;C(O)&#x2014;NH]-A, wherein Ris a Cto Cperfluoroalkyl; X is a divalent radical; n is 0 or 1; R1 is H or Cto Calkyl; m is 1 to 20; p is a positive integer of at least 2; and A is the residue of a polyisocyanate, and methods for altering surface behavior of liquids using such compounds.

Fluorinated ethoxylated polyurethanes

A solvent-based non-aqueous fluorinated methacrylate polymer comprising repeating units in any sequence from (1) at least one fluorinated methacrylate, and (2) at least one non-fluorinated alkyl acrylate and (3) at least one non-fluorinated hydroxyalkyl methacrylate,

Non-aqueous composition comprising partially fluorinated methacrylic polymers

A composition for imparting surface properties to substrates comprising a polymer of at least one polyurethane having at least one urea linkage prepared by:

Fluoropolymer compositions and treated substrates

A polymer having at least one carbamate linkage prepared by: (i) reacting (a) at least one diisocyanate, polyisocyanate, or mixture thereof, and (b) at least one fluorinated compound selected from the formula (I):R(CH)[(CFCF)(CHCH)](R1)&#x2014;xH&#x2003;&#x2003;(I)

A polymer having at least one carbamate linkage prepared by: (i) reacting (a) at least one diisocyanate, polyisocyanate, or mixture thereof, and (b) at least one fluorinated compound selected from the formula (I):R(CH)[(CFCF)(CHCH)](R1)-xH&#x2003;&#x2003;(I)
