Patent number: 5942563Abstract: An aqueous protective coating composition particularly useful for can coatings is based on a polymeric binder comprising epoxy crosslinked microgel particles. The microgel polymer is produced by dispersing into water a carboxyl functional, acrylic-epoxy grafted copolymer, and combined with a high molecular weight, branched, multifunctional epoxide resin, followed by coreaction and crosslinking between the carboxyl copolymer and branched epoxide to form stable aqueous dispersed microgel particles. In a preferred aspect of the invention, low molecular weight liquid diepoxide is dispersed into and crosslinked with the carboxyl functional acrylic grafted epoxy copolymer.Type: GrantFiled: July 18, 1997Date of Patent: August 24, 1999Assignee: The Glidden CompanyInventor: Henry J.

Patent number: 5733970Abstract: An aqueous protective coating composition particularly useful for can coatings based on a polymeric binder comprises water dispersed diepoxide crosslinked microgel particles. The microgel polymer is produced by disposing in water a carboxyl functional, addition polymer modified, maleated glyceride oil copolymer and crosslinking aqueous disposed carboxyl copolymer with a low molecular weight diepoxide to form stable aqueous disposed microgel particles. The maleated glyceride oil can be modified by in-situ polymerizing ethylenic monomers with the maleated glyceride oil in the absence of water or in water to form either a water dispersed copolymer or an aqueous emulsion copolymer. The water disposed copolymer is subsequently heat reacted with diepoxide mixed with the copolymer to form aqueous dispersed microgel polymer particles.Type: GrantFiled: January 28, 1997Date of Patent: March 31, 1998Assignee: The Glidden CompanyInventor: Gary P.

Patent number: 5576360Abstract: A coating composition substantially free of volatile organic compounds and containing a film-forming polymeric binder comprising epoxy crosslinked microgel particles having a particle size less than about 0.15 microns. The microgel particles are produced by first dispersing carboxyl functional addition copolymer dispersant into water followed by dispersing carboxyl functional polyester oligomer and diepoxide resin into the aqueous dispersant, and then esterifying the epoxy resin with the carboxyl functionality on the copolymer and oligomer. In a further variation, the polyester oligomer can contain maleic or fumaric unsaturation and subsequently grafted with in-situ copolymerized ethylenic monomers.Type: GrantFiled: July 14, 1994Date of Patent: November 19, 1996Assignee: The Glidden CompanyInventors: Gary P.

Patent number: 5576361Abstract: Protective coating compositions free of volatile organic solvents and particularly useful as can coatings are produced based on an aqueous dispersed microgel polymeric binder comprising between about 1% and 70% low molecular weight polyester diluent, between about 1% and 70% epoxy resin, between about 10% and 80% addition copolymer, and between about 1% and 40% low molecular weight diepoxide crosslinking resin. The aqueous dispersed solvent free microgel polymer is produced by mixing the polyester diluent with high molecular weight epoxy to produce a fluid resin mixture, copolymerizing in-situ ethylenically unsature monomers including carboxyl monomers in the presence of the fluid resin mixture and dispersing the resulting polymeric mixture into water. Low molecular weight diepoxide resin is added and crosslinked with carboxyl functionality to produce the microgel polymers.Type: GrantFiled: April 20, 1995Date of Patent: November 19, 1996Assignee: The Glidden CompanyInventor: Gary P.
