Patent number: 7842177Abstract: A pigmented granular pigmented coating feedstock is prepared by melting a resin, which can be a solid resin based on polymerizable ethylenically unsaturated monomer or epoxy based resin, and a solid or viscous curing agent, blending the molten mass, and cooling to form a solid. The solid blend of resin and curing agent is ground to produce a granular feedstock. The feedstock is readily storable or shippable to a location for coating preparation. Alternatively a solid coating can be ground after shipping. An aqueous coating is made by dispersing the feedstock in water and mixing to form a dispersion. A salting agent and at least one additive can be added to form an aqueous coating composition. An article can be coated with the dispersion, for example, by electrodeposition.Type: GrantFiled: October 29, 2007Date of Patent: November 30, 2010Assignee: BASF Coatings GmbHInventor: Charles L. Tazzia

Patent number: 7838582Abstract: A hyperdispersant for use in a fluorocarbon coating composition is disclosed. The fluorocarbon coating composition generally comprises a fluorocarbon resin, a binder resin, a cross-linking agent, and the hyperdispersant. The hyperdispersant comprises the reaction product of a polyglycidyl oligomer and at least one amino compound. The polyglycidyl oligomer comprises a carbon chain having from 1 to 25 carbon atoms with at least one of an internal ether linkage and an internal ester linkage and comprises a plurality of epoxy groups. The at least one amino compound has a cyclic, heterocyclic, alkyl, or heteroalkyl structure substituted with at least one primary or secondary amine group for reacting with and opening at least one of the epoxy groups.Type: GrantFiled: March 12, 2007Date of Patent: November 23, 2010Assignee: PPG Industries Ohio, Inc.Inventors: James L. Anderson, David Lindow, Donald J. Algrim
