Abstract:
Water-based compositions that are resistant to dirt pickup are described. The water-based composition includes a latex or water-dispersible polymer and a non-VOC UV-VIS (preferably, ultraviolet) absorber as a dirt pickup resistance additive. Methods of making water-based compositions including a non-VOC UV-VIS absorber as a dirt pickup resistance additive are also described.
Abstract:
An article, comprising a food or beverage container (20), or a portion thereof, that includes a metal substrate (30, 32) and a coating (34) disposed on at least a portion of the metal substrate (30, 32). The coating (34) is preferably formed from a coating composition that comprises an emulsion polymerized latex having a first-stage emulsion polymerized copolymer and a second-stage emulsion polymerized copolymer.
Abstract:
An article, comprising a packaging article such as food or beverage container (20), or a portion thereof, that includes substrate (30, 32) and a coating (34) disposed on at least a portion of the substrate (30, 32). The coating (34) is preferably formed from a coating composition that comprises a latex emulsion having a first-stage copolymer, a second-stage copolymer, and a linkage interconnecting the first-stage copolymer and the second-stage copolymer prior to curing.
Abstract:
The present disclosure relates to an aqueous dispersion for sustained release of a functional component useful for a coating composition, and a preparation process and use thereof. The aqueous dispersion comprises polymeric particles with a polymeric core-shell structure and the functional component contained in the polymeric core of the polymeric particles, wherein the polymeric shell has Tg of 20° C. or less, and wherein the functional component has a water solubility of 10 g/100 g water or less at room temperature.
Abstract:
The present description provides a water-reducible or water-dispersible coating system that can be used to form a durable, corrosion-resistant protective coating on a wide range of substrates. The coating system includes an alkyd resin prepared from a polyester feedstock that includes post-consumer recycled PET and a waste cooking oil feedstock. Methods for preparing the coating system and articles coated with the coating system are also described.
Abstract:
Di(amido(alkyl)phenol) compounds and upgraded molecular weight polymers made from such compounds have particular utility in coating compositions, especially for use on food and beverage contact substrates that are formed into or will be formed into containers or container components.
Abstract:
A polymer is provided that preferably includes at least one unsaturated cycloaliphatic group. In one embodiment, the polymer is combined with an optional crosslinker and an optional carrier to form a coating composition suitable for use in coating articles such as packaging articles. In one embodiment, the polymer has at least one unsaturated cycloaliphatic group that is at least bicyclic.
Abstract:
The present invention provides coating systems that use polycyclic polyester resins in combination with phenolic resins. The combination of these resin materials provides a coating composition that provides cured coatings with excellent adhesion, blush resistance, stain resistance, and corrosion resistance in a single coating composition. This makes the coating compositions well suited for use to form coatings on closures used in the packaging industry for food and beverages. In many embodiments, even though PVC and BPA materials are excluded, the coating compositions provide monocoats whose performance substantially matches and even exceeds the performance of monocoats formed from PVC and BPA containing materials.

White-pigmented and unpigmented base paints and stains are custom-tinted using an automated colorant dispenser having a minimum fluid dispensing quantity less than 0.01 fluid ounce (
Abstract:
A polymer-encapsulated pigment dispersion is prepared from a mixture of (a) a carrier; (b) pigment particles; and (c) a polymeric dispersing agent having a polymer backbone, and a zwitterionic polymer side chain comprising anionic and cationic groups. The dispersing agent may provide efficient pigment wetting and dispersion using relatively low and thus economical pigment amounts, with good opacity and good hiding characteristics, especially in titanium dioxide-containing coating compositions
