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 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.

Novel silane compositions have been prepared by reacting a 3-isocyanatopropyl trialkoxysilane with an alcohol or diol having a divalent alkylene or alkylene-ether group. The alcohol or diol has a formula weight less than about 5000. The compositions can be used to modify the surfaces of inorganic oxygen-containing materials, including but not limited to silica, silicates, borosilicates, aluminosilicates, days, and metal oxides. Surface treatment of silica nanoparticles with these compositions improves their improved dispersion in polyester nanocomposites.

Silane compositions for polyester nanocomposites

Polyester nanocomposite compositions contain silica nanoparticles that have been subjected to surface treatment with novel trialkoxysilane compositions. The novel silane compositions are prepared by reacting a 3-isocyanatopropyl trialkoxysilane with 1,3-propanediol or certain polyether diols. The silica nanoparticles exhibit improved dispersion in the polyester. This leads to haze reduction and improvements in mechanical properties.
