摘要:
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.
摘要:
A polyester polymer is provided that includes at least one pendant phenolic-containing group. In one embodiment, the polyester 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. The coating composition typically includes a resole phenolic crosslinker. In one embodiment, the polyester polymer has at least one phenolic-containing group that comprises an adduct of cardanol.
摘要:
A polyester-carbamate polymer and coating compositions containing the polymer are provided. The polyester-carbamate polymer preferably includes a polyester-carbamate backbone and one or more blocked isocyanate groups. A coating composition is provided that preferably includes the polyester-carbamate polymer and a thermoplastic dispersion. In a preferred embodiment, the coating composition is an organosol.
摘要:
Food and beverage containers and methods of coating are provided. The food and beverage containers include a metal substrate that is at least partially coated with a coating prepared from a composition that includes a resin system, a crosslinker, and a catalyst. Preferably, the coating composition is substantially Bisphenol A-free.
摘要:
Food and beverage containers and methods of coating are provided. The food and beverage containers include a metal substrate that is at least partially coated with a coating composition that includes a water-dispersible resin system and an aqueous carrier. The resin system includes an epoxy component and an acrylic component. In a preferred embodiment, the coating composition is at least minimally retortable when cured.

摘要:
A polymer and coating compositions containing the polymer are provided that are useful in coating applications such as, for example, food or beverage packaging coatings. The polymer preferably includes a polyester backbone and at least one deblockable isocyanate group attached to the backbone. In one embodiment, the polymer includes a polyester-carbamate backbone, one or more pendant deblockable isocyanate groups, and one or more terminal or pendant isocyanate-reactive groups. The deblockable isocyanate groups may be provided, for example, through use of a partially blocked polyisocyanate.
摘要:
A polymer and coating composition containing the polymer are provided that are useful in coating applications such as, for example, food or beverage packaging containers. The polymer preferably includes a backbone having one or more polycyclic groups. In one embodiment, the polymer is a polyester and, more preferably, a polyester-urethane polymer. In one embodiment, the one or more polycyclic groups is a tricyclic or higher group.
