Powder coating compositions, particularly metal packaging powder coating compositions, coated metal substrates, and methods; wherein the powder coating compositions include powder polymer particles comprising a polymer having a number average molecular weight of at least 2000 Daltons, wherein the powder polymer particles have a particle size distribution having a D50 of less than 25 microns; and, in certain embodiments, one or more charge control agents in contact with the powder polymer particles.

Metal packaging powder coating compositions, coated metal substrates, and methods

The disclosure provides a functionalized polymer for use in coating compositions and a method for making the functionalized polymer. In some embodiments, the functionalized polymer is a water-dispersible polymer, more preferably a water-dispersible polyester polymer, having one or more side groups including one or more salt groups. Packaging containers (e.g., food or beverage cans) comprising the functionalized polymer and methods of making such containers are also provided.

Methods and materials for the functionalization of polymers and coatings including functionalized polymer

A liquid polymeric coating composition that upon application to a substrate, such as a coil substrate, preferably does not exhibit the edge build and edge blistering that commonly occurs with conventional liquid polymeric coating compositions. In some embodiments, the liquid polymeric coating composition is modified by tailoring the surface tension, the openness of the coating composition as indicated by the modulus of elasticity, or a combination thereof to reduce edge build and edge blistering. The modified liquid polymeric composition may be applied to a surface of the substrate and cured to form a film coating that reduces or alleviates commonly encountered edge defects in conventional liquid polymeric coating compositions, such as edge build and edge blistering, which may avoid the need for edge trimming of the coated substrate. The coated coil substrate is well suited for forming food or beverage containers or portions thereof.

Edge build and edge blister performance of coil coatings

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.

Polymer having unsaturated cycloaliphatic functionality and coating compositions therefrom

The invention provides polymer particles useful in a variety of applications, including coating applications such as packaging coatings. The polymer particles preferably have a volume-averaged particle size of less than 40 microns, more preferably less than 20 microns. In preferred embodiments, the polymer particles are precipitated particles, more preferably precipitated polyester particles, which are optionally free of low-molecular weight surfactant.

Polymer particles and coating compositions formulated from the polymer particles

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.
