Food cans coated at least in part on the interior with a composition comprising an acrylic polymer and a crosslinker are disclosed. The composition is substantially epoxy-free and substantially polyester-free. The acrylic polymer has a weight average molecular weight of greater than or equal to 41,000 and an acid value of
摘要:
A composition for coating food cans is disclosed. The composition comprises a polyester, an acrylic copolymer and a crosslinker; the polyester and acrylic copolymer have been compatibilized in some way, such as through graft copolymerization. Methods for compatibilizing acrylics and polyesters are also disclosed as are methods for coating cans using compositions comprising acrylic and polyesters.
摘要:
A polyester prepared by free radical polymerization of an unsaturated polyester prepolymer, wherein the polymerization occurs primarily by reaction of the unsaturation is disclosed. Coatings comprising the same are also disclosed, as are substrates coated at least in part with such coatings.

A non-aqueous dispersion comprising the dispersion polymerization reaction product of an ethylenically unsaturated monomer and a polyester stabilizer in solvent is disclosed, as are coatings comprising the same and substrates coated at least in part with such coatings.
摘要:
Polyesters comprising the reaction product of a polyol and a bis-epoxy reacted with a mono- and/or di-phenolic carboxylic acid and/or ester are disclosed. Food cans coated at least in part on the interior with a composition comprising these polyesters are also disclosed. The composition used on the food cans is substantially free of BPA and BPF and substantially free of BADGE and BFDGE. Food cans coated at least in part on the interior with a composition comprising a polyester having a loss of molecular weight of less than 50% in an acidic medium are also disclosed.
摘要:
This invention provides a novel phosphatized polymeric product which is formed by: (a) forming an amine-extended resinous composition having unreacted epoxy groups by mixing, under free-radical initiated polymerization conditions, a polymerizable, ethylenically unsaturated monomeric component and a polyepoxide component; and (b) phosphatizing at least a portion of the unreacted epoxy groups of the resinous composition. The present invention also provides novel coating compositions containing the aforedescribed polymeric product. While these novel coating compositions have a number of different uses, they are particularly useful for application to metal substrates such as can end stock since they result in a cured film which has excellent performance properties such as flexibility and extensibility, adhesion, resistance to boiling liquid pack tests and boiling water taste test results.
