Abstract:
This invention provides a polymer that is useful in a variety of applications, including as a binder polymer of a coating composition, and especially a packaging coating composition. Packaging articles (e.g., containers) comprising the polymer and methods of making such packaging articles are also provided.
Abstract:
Se proporciona un polímero de poliéster que incluye al menos un grupo que contiene fenol colgante. En una modalidad el polímero de poliéster se combina con un reticulador opcional y un portador opcional para formar una composición de recubrimiento adecuada para usar en artículos recubiertos tales como artículos de envase. La composición de recubrimiento incluye, por lo general, un reticulador de resol fenólico. En una modalidad el polímero de poliéster tiene al menos un grupo que contiene fenol que comprende un aducto de cardanol.
Abstract:
Se proporcionan recipientes para alimentos y bebidas y métodos de revestimiento. Los recipientes para alimentos y bebidas incluyen un substrato metálico que es al menos parcialmente revestido con un revestimiento preparado a partir de una composición que incluye un sistema de resinas, un entrelazador y un catalizador. De preferencia, la composición de revestimiento está sustancialmente libre de bisfenol A.
Abstract:
Food and beverage containers and methods of coating are provided. The foo d and beverage containers include a metal substrate that is at least partial ly coated with a coating prepared from a composition that includes a resin s ystem, a crosslinker, and a catalyst. Preferably, the coating composition is substantially Bisphenol A-free.
Abstract:
The present invention provides aqueous dispersions that comprise the reaction product of (A) a polyester that is a reaction product of at least a (i) polybasic acid containing at least two carboxyl groups and (ii) a polyhydric alcohol containing at least two hydroxyl groups and (B) at least (i) a (meth)acrylic acid ester, and (ii) an ethylenically unsaturated mono- or multi-functional acid. Also described are coating compositions containing the aqueous dispersion, methods of forming the aqueous dispersion, and metal containers bearing internal liners derived from the coating compositions with beverages or wet foodstuffs located in the metal containers and in contact with the internal liners.
Abstract:
Powder compositions and articles and methods of forming articles from powder compositions are provided. The powder compositions include at least one powder that preferably includes an amount of one or more branched polymers such as, for example, one or more branched polyamide polymers. The powder composition is preferably capable of being formed, via a layer-by-layer sintering process such as, for example, selective laser sintering, into a three-dimensional article.
Abstract:
The present invention provides novel packaging articles, e.g., food and beverage cans, having a novel coating composition applied to at least a portion of a surface thereon. In preferred embodiments, the coating composition includes at least a film-forming amount of a copolyester resin having a backbone that includes one or more soft segments and a plurality of hard segments. The copolyester resin preferably has a glass transition temperature from about from about 10° C. to about 50° C. The present invention also provides a method for making coated articles.
