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： 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.

摘要： The invention provides a novel coating composition which includes: (a) a polyester-based resin component, (b) an epoxy component, (c) a cross-linker component, (d) a catalyst component, and (e) a diluent component. The polyester-based resin component includes at least one phosphatized polyester resin; and the epoxy component includes at least one phosphatized epoxy resin. These coating compositions are particularly suitable as primers, and especially as primers for use used in conjunction with coating composition which include fluorocarbon polymers. Also provided is a method of providing a substrate with a multilayer coating system. This method includes: (a) applying at least one layer of the aforementioned novel primer onto a substrate; and (b) applying at least one layer of a second coating composition over the primed substrate of step (a). When this method employs the use of a second coating composition which includes fluorocarbon polymers, the result is multi-layered coated substrate which, while having excellent weatherability properties, also has excellent formability properties.
