    摘要: A protective coating composition for coating interior surfaces of beer, beverage, and food containers, as well as interior and exterior surfaces of can ends, comprises a polymeric binder of emulsion copolymerized ethylenic monomers in the presence of an unsaturated polyester dispersed into water with an aqueous dispersed epoxy-acrylic graft copolymer dispersant. The preferred polymeric binder comprises by weight between 0.1% and 40% unsaturated polyester, between 20% and 80% emulsion copolymerized ethylenic unsaturated monomers, and at least 20% dispersant, where the emulsion copolymerized monomers crosslink with the water dispersed unsaturated polyester.

    摘要: Coating compositions containing aqueous dispersion of higher molecular weight epoxy resin are produced by advancing the molecular weight of an aqueous dispersion of a low molecular weight epoxy resin having a number average molecular weight between about 360 and 2,000. The water dispersed low molecular weight epoxy resins are advanced in molecular weight by coreaction with diphenol at temperatures above about 105.degree. C. and at pressures above about 5 psig to produce the aqueous dispersed high molecular weight epoxy resin. The aqueous dispersed high molecular weight epoxy resin can be further copolymerized with ethylenic monomers, if desired, to produce an acrylic epoxy emulsion binder useful protective coatings.

    摘要: A solid electrolyte oxygen sensor has a protective coating to protect a catalyst or conductive film thereon, which coating is formed as an inorganic reaction product of an oxide material and an inorganic acid which forms a matrix to bond the oxide material as an adherent coating over the film.
