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 a composition and method of use for providing cleanability to paint comprising an aqueous emulsion of Formula (I) wherein the composition of Formula (I) is a random copolymer; wherein said composition of formula (I) further comprises residue from a hydrophilic chain transfer agent. 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. For these reasons, the composition of the present invention is particularly suitable for use as additives to exterior coatings and paints.
