    Abstract: Disclosed is an anionic, self-emulsified aqueous epoxy resin dispersion prepared through the semi-esterification reaction between a dicarboxylic acid anhydride and the secondary hydroxy group of an epoxy resin, followed by neutralization of the carboxylic acid thus introduced into the epoxy resin with a tertiary amine and then adding only water, without the need of any emulsifier, to the resulting hydrophilic amine salt of the carboxylic acid. The stable aqueous epoxy resin contains both carboxyl and epoxy groups which are reactive functional groups. Also disclosed is a “single-pack” curable aqueous epoxy resin system “cross-linkable” at normal temperature prepared by adding a compound containing polyaziridine as a cross-linking agent into the aqueous epoxy resin dispersion. Upon drying, the liberated carboxyl group in the aqueous epoxy resin reacts with the polyaziridine to form an amino ester via a ring opening reaction.

  • Patent number: 5576360
    Abstract: 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.

  • Patent number: 5554671
    Abstract: An aqueous dispersed, very low VOC (less than about 0.4 pounds per gallon), protective surface coating composition comprises crosslinked microgel particles of less than 1 micron and produced by dispersing low molecular weight carboxyl functional addition copolymer into water, stably dispersing diepoxide epoxy resin in the aqueous dispersion, and coreacting the diepoxide resin with the carboxyl functional copolymer to provide epoxy-ester crosslinked microgel polymer particles stably dispersed into water. The microgel particles are useful as a polymeric binder for aqueous dispersed coatings particularly useful for coating interior surfaces of beer and beverage cans.

  • Patent number: 5548018
    Abstract: An aqueous primer composition comprising a copolymer wherein a cationic monomer, a specific alkoxysilane monomer, a silane macromonomer and an ethylenically unsaturated monomer are contained in aqueous medium. For this reason, regardless of the alkalinity of the substrate, the aqueous primer composition can form a highly water-resistant, alkali-resistant, tough film. Furthermore, compared with the prior art, a higher concentration and a lower viscosity, so that the resulting primer composition shows excellent penetration into the substrate at high concentration and provides for sufficient substrate-reinforcing and water-proofing effects. Moreover, when forming a film thereby and forming a finish layer thereon, this composition shows a high affinity for the top coating or adhesive to insure a firm integration of the finish layer with the substrate surface.

  • Patent number: 5532297
    Abstract: The invention pertains to aqueous dispersed, crosslinked microgel polymers useful as a polymeric binder in protective coatings. The microgel polymeric binder comprises epoxy-acrylic graft copolymer dispersed into water, emulsion copolymerized monoethylenically unsaturated monomer, and emulsion copolymerized divinyl benzene adapted to crosslink in the emulsion copolymerization step with the monoethylenic monomers to produce the crosslinked microgel polymer particles. The microgel polymer is particularly useful as binder for can coatings adapted to be heat cured to form a protective film.

  • Patent number: 5296525
    Abstract: A coating composition particularly adapted for can coatings is prepared by the addition polymerization of a monomer such as styrene in a reaction medium comprising a modified 1,2 epoxy resin. The epoxy resin is modified by combining a portion of its 1,2-epoxy groups with epoxy-reactive groups of an ethylenically unsaturated monomer, and reacting others of its 1,2-epoxy groups with a tertiary amine and with a preformed addition polymer containing carboxyl groups to form an ionic, resinous composition containing sufficient carboxyl groups to render the coating composition self-dispersible in water in neutralized form.

  • Patent number: 5268452
    Abstract: Unsaturated polyester resins of the type already having reactive liquid polymers reacted into the backbone of the resins, are cured in the presence of a reactive liquid polymer additive admixed with the prereacted unsaturated polyester resin. Heating of this system during cure causes the reactive liquid polymer additive to miscibilize with the unsaturated polyester resin. The unsaturated polyester resin modified in the manner described above shows a significant enhancement in toughness as measured by fracture energy over unmodified counterparts or counterparts modified by known methods of adduction or admixing alone.

  • Patent number: 5091447
    Abstract: A method and composition for providing a polymeric membrane in situ for isolating vessels which hold hazardous liquid materials. A liquid polymer composition is applied to at least one of the surfaces defining the area which is to hold the liquid hazardous material. Upon cure, a seamless bladder-like membrane is formed which adheres to the surface, and which can be removed by physically peeling from the surface to which it has been applied. The membrane possesses a unique combination of properties which are substantially maintained while in contact with the hazardous material. The polymeric membrane provides, for an extended period of time, an impermeable barrier which acts as a secondary sealant and prevents the spread, deposition, or migration of contaminants.
