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.

Fluorinated polymer additives derived using hydrophilic chain transfer agents for architectural coatings

A stain resistant, oil and water repellent copolymer comprising a copolymer prepared from fluorinated (meth)acrylate and amine salts of (meth)acrylic acid, and a method of providing stain resistance, oil and water repellency to substrates and a treated substrate.

Fluorinated copolymers of (meth)acrylates and (meth)acrylic acid amine complexes

A method to provide acid etch resistance to contacting a calcareous substrate with a copolymer prepared from fluorinated methacrylate, short chain branched (meth)acrylate, and (meth)acrylic acid salt and a treated substrate.

Acid etch resistance for calcareous substrates

The present invention relates to in situ polymerization of fluoropolymer into porous substrates, to improve resistance to degradation by wetting and staining, and wood, to improve resistance to degradation, staining and warping.

In situ fluoropolymer polymerization into porous substrates

Polymer compositions containing a mixture of an elastomer and a fluoropolymer can be made by diffusing fluorinated olefins and free radical initiators in preferably swollen elastomers and polymerizing the fluorinated olefins. The resulting compositions have useful properties, such as reduced sliding friction, which makes them useful for seals in contact with moving surfaces, and for other uses.
