Patent number: 4447580Abstract: A resin composition comprising (A) a polymer having, in the molecule, at least two groups represented by the following structural formula (I): ##STR1## wherein R.sub.1 is isopropyl, sec-butyl, tert-butyl, a C.sub.5-20 alkyl group, a C.sub.3-20 cycloalkyl group, a C.sub.5-20 alkenyl group, a C.sub.3-20 hydroxyalkyl group, a C.sub.5-20 alkoxyalkyl group, a C.sub.3-20 aminoalkyl group, a C.sub.6-20 aryl group or a C.sub.6-20 arylalkyl group, and n is 0, 1 or 2, and (B) a polymer having an electron attractive group and an .alpha.,.beta.-ethylenic double bond adjacent thereto. Though said composition is stable at room temperature, it is crosslinked and cured at high temperatures because the amino group of the polymer (A) adds to the double bond of the polymer (B). Accordingly, said resin composition is suitable for use as a cathodic electrocoating material.Type: GrantFiled: November 12, 1981Date of Patent: May 8, 1984Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Hideo Ai, Naohiro Tsuruta

Patent number: 4431689Abstract: A process is provided for coating a substrate by applying to a substrate an aqueous coating composition that comprises (a) an aqueous dispersion of a film forming polymer having a minimum film forming temperature not higher than 45.degree. C.; (b) a solid, particulate polymer having a softening temperature in the range of 45.degree. to 260.degree. C. and an average particle size in the range of 2 to 400 .mu.m and (c) a solid, rubberlike polymer having an average particule size in the range of 1 to 500 .mu.m, the resulting coating being cured at a temperature of 70.degree.-260.degree. C. The invention also relates to the liquid aqueous coating composition to be used in said process.Type: GrantFiled: May 21, 1982Date of Patent: February 14, 1984Assignee: Akzo N.V.Inventor: Gerhard Gunter

Patent number: 4421878Abstract: The invention herein disclosed provides a method for preparing improved fluoroelastomer film compositions including the steps of dissolving a fluoroelastomer gum selected from the group consisting of copolymers of vinylidene fluoride and hexafluoropropylene, and terpolymers of vinylidene fluoride, hexafluoropropylene and tetrafluoroethylene in a solvent, adding an amine-derived curative to the gum solution and curing the fluoroelastomer gum with the curative in the absence of metallic oxides. A method is also provided for adhering fluoroelastomer film compositions, devoid of metallic oxides, to substrates which includes the steps of dissolving the fluoroelastomer gum in a solvent, adding an amine-derived curative to the gum solution, coating the substrate with the fluoroelastomer gum-curative solution and evaporating the solvent leaving a film firmly adhered to the substrate.Type: GrantFiled: November 25, 1981Date of Patent: December 20, 1983Assignee: David Hudson, Inc.Inventor: Donald Close

Patent number: 4342843Abstract: The metal adhesion and heat and water resistance of conventional neoprene latex adhesives are improved by the addition thereto of a polyamine and an epoxy resin wherein for every 100 parts by weight of dry neoprene, the epoxy is added in an amount of 10-40 parts and the amine is added in an amount sufficient to provide 50-150% of the stoichiometric amount required to cure the epoxy.Type: GrantFiled: February 24, 1981Date of Patent: August 3, 1982Assignee: National Starch and Chemical Corp.Inventors: Witold Perlinski, Irwin J. Davis, John F. Romanick

Patent number: 4324715Abstract: A coating composition comprising a dispersion of an epoxy resin, a nitrogen resin crosslinker such as a melamine formaldehyde, a particulate fluorocarbon such as PTFE, and citric acid can be applied to substrates such as polysulfones and cured at low temperatures on the order of 107.degree. C. The resulting coating is especially useful as a barrier to seal the surface of the substrate and to improve abrasion resistance.Type: GrantFiled: October 29, 1980Date of Patent: April 13, 1982Assignee: E. I. DuPont de Nemours and CompanyInventor: Dennis P. Emerick

Patent number: 4306953Abstract: Photopolymerizable compositions using sulfonium salt photoinitiators to effect polymerization of cationically polymerizable monomers additionally include a stable free radical to reduce or eliminate the sulfur odor generated upon photodecomposition of the sulfonium salt photoinitiator. The stable free radicals are soluble in the polymerizable material and are stable in the composition at ambient temperatures. Especially useful is 2,2-diphenyl-1-picrylhydrazyl.Type: GrantFiled: November 5, 1979Date of Patent: December 22, 1981Assignee: American Can CompanyInventor: Sheldon I. Schlesinger
