This invention provides a polymer, which is preferably a polyether polymer. The polymer may be uses in coating compositions. Containers and other articles comprising the polymer and methods of making such containers and other articles are also provided. The invention further provides compositions including the polymer (e.g., powder coatings), which have utility in a variety of coating end uses, including, for example, valve and pipe coatings.

A food or beverage container, or portion thereof, including a metal substrate and a coating on at least a portion of the metal substrate, the coating formed being from a coating composition comprising a polymer having one or more substituted or unsubstituted spirocyclic segments such as substituted or unsubstituted segments of 2,4,8,10-tetraoxaspiro [5.5] undecane.

A relatively low cost, two component solvent-based urethane coating, intended to protect steel shipping containers made from modified drying oils.

The invention relates to a process for preparing an organic solvent-based dispersion comprising a melt-blended network of an epoxy-functional and/or amino-functional polymer having a polymer-O—Si—O-polymer linkage and a polyolefin (co)polymer having carboxylic acid and/or carboxylic acid anhydride groups, the process comprising the steps of a) forming the melt-blended network from a prepolymer, a silane-functional compound and the polyolefin (co)polymer in the absence of a solvent, b) mixing the melt-blended network with an organic solvent to make the organic solvent-based dispersion, and c) cooling the organic solvent-based dispersion. The invention further relates to a coating composition and to a coated metal substrate.

Coated packages and methods for coating such packages is disclosed The coating compositions comprise a carboxyl-containing polymer and a polycarbodiimide.

The present invention relates to a polyketone copolymer consisting of repeating units represented by general formulae (3) and (4) below, and a mixture composition thereof. The present invention has excellent has barrier properties and thus can be used for vehicle fuel tanks, vehicle hydrogen tank liners, sealed food containers, etc.

—(CH2CH2—CO)x—  (3)

—(CH2CH(CH3)—CO)y—  (4)

(wherein x and y denote the mol % of each of the general formulae (3) and (4) in a polymer).

This invention provides a coating composition that contains an aromatic adhesion promoter. Containers and other articles comprising the coatings and methods of making such containers and other articles are also provided. The invention further provides compositions including the adhesion promoter, which have utility in a variety of coating end uses, including, for example, valve and pipe coatings.

A unique flexible container combination comprises a viscoelastomeric thermoset overlay disposed upon a flexible supportive base. Desirably, the viscoelastomeric thermoset overlay possesses exceptional adhesive, cohesive and releasability properties. In some embodiments, the flexible container combination can also exhibit antipathogenic, cleansability and/or reusability properties. The flexible container combination can maintain an adhered stowable item in an immobilized position until intentionally removed therefrom by a user. In some embodiments, the flexible container combination can be folded or rolled into a rolled-up configuration.

A copolymerized saturated polyester resin is formed by polycondensation of an acid component and an alcohol component. The acid component contains (a-1) 90 to 99% by mole of an aromatic dicarboxylic acid or a C.sub.1-2 alkyl ester thereof and (a-2) 0.5 to 2% by mole of a trifunctional or higher functional carboxylic acid or an anhydride thereof. The alcohol component contains (b-1) 45 to 80% by mole of an alicyclic polyhydric alcohol and (b-2) 20 to 55% by mole of an aliphatic polyhydric alcohol having a C.sub.1-3 alkyl side chain. A coating composition containing the copolymerized saturated polyester resin shows excellent corrosion resistance and chemical resistance. A coating film formed from the coating composition shows excellent processability and resin solubility, and is useful for coating a can and pre-coated metal.

A powder coating composition comprising: a) a thermoset resin comprising an acid functional polyester material, b) a thermoplastic resin and c) a crosslinker material,
wherein the coating composition is substantially free of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE).
