Patent number: 5162427Abstract: Heat cured, thermoset protective surface coating films applied to a substrate are produced preferably by a dual cure of a polymeric ionomeric binder comprising zinc modified carboxyl functional epoxy-ester polymers. The epoxy-ester polymer contains both carboxy and hydroxyl functionality and coreacts with a zinc salt selected from a zinc carbonate or an organic zinc salt having a pKa above about 3.0. Upon heat curing, the carboxyl and hydroxyl groups crosslink while the zinc forms a zinc cluster to produce a thermoset film.Type: GrantFiled: January 22, 1991Date of Patent: November 10, 1992Assignee: The Glidden CompanyInventors: Gary P. Craun, Barbara L. Kunz

Patent number: 5157073Abstract: Non-aqueous ionomeric coatings useful as protective surface coatings applied to a substrate are produced by combining a carboxyl functional polymer with zinc carbonate. Upon heat curing the applied film, the zinc cation clusters with the carboxyl polymer to produce a thermoset coating film.Type: GrantFiled: April 15, 1991Date of Patent: October 20, 1992Assignee: The Glidden CompanyInventor: Barbara L. Kunz

Patent number: 5015687Abstract: The pigmented paint coating composition is based on a cationic free polymeric binder comprising a cationic free, functional emulsion polymer and glycoluril where the emulsion polymer are adapted to coreact to form a thermoset paint film, and said polymeric binder is combined with a low-cation opacifying pigment. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers but excluding amine monomers, in an aqueous polymerization medium, to produce the reactive emulsion polymer. The emulsion polymer and the glycoluril derivative are treated with ion-exchange step to produce the cation-free polymeric binder.Type: GrantFiled: November 7, 1989Date of Patent: May 14, 1991Assignee: The Glidden CompanyInventors: Kenneth G. Hahn, Jr., Barbara L. Kunz

Patent number: 4981883Abstract: A stabilized aqueous, thermosetting coating composition substantially free of acid cure catalysts comprises a mixture of an ion-exchanged reactive function emulsion polymer and a glycoluril derivative adapted to coreact and crosslink the functional polymer where certain cations are added to the ion-exchanged mixture to provide a pH of the mixture between 2 and 5.Type: GrantFiled: January 12, 1990Date of Patent: January 1, 1991Assignee: The Glidden CompanyInventors: Barbara L. Kunz, Kenneth G. Hahn, Jr.

Patent number: 4624762Abstract: A cathodic electrocoating paint composition that yields solvent-resistance films is shown. The paint binder consists essentially of:(a) synthetic cation-active latex and resinous pigment dispersant that is crosslinkable therewith, with the proviso that when said dispersant is substantially in excess of about 15% of said latex, an external crosslinker is present that will crosslink upon curing with at least said dispersant; or(b) synthetic cation-active latex and resinous pigment dispersant that is not crosslinkable therewith and external crosslinker that will crosslink with both said latex and said dispersant.Type: GrantFiled: April 15, 1985Date of Patent: November 25, 1986Assignee: SCM CorporationInventors: Kirk J. Abbey, David J. Foss, Barbara L. Kunz
