Abstract: Mixtures of (1) reaction products obtained from (a) epoxides, for example polyglycidyl ethers of bisphenol A, (b) primary amines having 2 to 8 carbon atoms and (c) polymerized fatty acids, for example dimerized or trimerized linoleic acids and linolenic acids, and optionally (d) difunctional compounds, for example epichlorohydrin, acrylic acid or acrylonitrile, and (2) aminoplast precondensates, for example methylolated and lower alkyl-etherified melamine or urea, are useful as leather finishes and are preferably employed in the form of organic-aqueous emulsions.

Abstract: Polyadducts, free from epoxide groups, are obtained from ammonia and epoxide compounds by reacting 1 mole of ammonia with from 1.2 to 2.0 equivalents of epoxide, so that if diepoxide compounds are used products of the general formula (I) ##STR1## are obtained, while if triepoxides and/or tetraepoxide compounds are used, by themselves, or together with diepoxide compounds, products of the general formula II ##STR2## are produced; in these formulae, the E.sup.1 's are identical or different hydroxyl-containing divalent radicals and the E.sup.2 's are identical or different hydroxyl-containing trivalent or tetravalent radicals, resulting from the opening of the oxirane rings of epoxide compounds containing two, three or four epoxide groups in the molecule, n.sup.1, n.sup.3 and n.sup.5 are from 0 to 3, n.sup.2 and n.sup.4 are from 1 to 3 and X is 0 or 1, and one or more of the divalent radicals E.sup.1 in the general formlula (II) may or may not be replaced by polyvalent radicals E.sup.2.

Abstract: Water reducible compositions useful as coating compositions for flexible substrates are prepared by reacting a glycidyl polyether of a dihydric phenol with a polyethylene glycol and ortho phosphoric acid.

Abstract: Coating compositions which may be applied by conventional techniques as well as by electrodeposition are provided by reacting a polyglycidyl ether of a polyphenol with an amino acid containing at least one amine group and one carboxyl group, wherein the amine group of the acid is preferentially reactive with the epoxy groups of the polyglycidyl ether. The resultant product can then be solubilized by neutralizing at least a portion of the acid functionality thereof with an amine or other base. Especially useful amino acids are the aminobenzoic acids.

Abstract: The present invention concerns a coating composition comprising a dispersion, solution or suspension of a coating composition containing a nitrogen containing organic material which when heat cured contains at least 75% less amine value than present in the material prior to curing.The present invention also concerns a method of electrodepositing a film forming substance onto a substrate by employing an anode, a cathode and an electrolyte therebetween comprising the steps:a. providing an aqueous electrolyte containing said composition described above;b. closing the circuit between the anode and the cathode; andc. depositing the film forming composition on the cathodic substrate.

Abstract: An aqueous sizing composition, method of preparing same and sized glass fibers are provided that enables the production of sized glass fibers having improved filamentization. The aqueous sizing composition has one or more cross-linkable film formers, one or more organo silane coupling agents and about 2 to about 12 weight percent of an interaction product of an unhydrolyzed or partially hydrolyzed amino organo silane coupling agent and an epoxidized polar thermoplastic copolymer. The epoxy copolymer has about 2 to about 12 parts of monomer with epoxy functionality per 100 parts of copolymer. Also the epoxy copolymer has a glass transition temperature (Tg) of from -10.degree. C. to about 70.degree. C. The unhydrolyzed or partially hydrolyzed amino silane coupling agent is contacted with the epoxidized copolymer, where the copolymer has a percent solids in the range of about 15 to about 60 weight percent.

Abstract: An aqueous sizing composition, glass fiber strands having the dried residue of the aqueous sizing composition and processes for producing these articles are provided that enable the production of glass fiber reinforced polymeric materials having improved properties. In addition, improvements are obtained in the processability of using glass fiber roving in the production of sheet molding compound, bulk molding compound and thick molding compound. The sizing composition, sized glass fiber strands, processes, reinforced polymeric materials and improvements of this invention emanate from the use of epoxidized polar thermoplastic copolymers in aqueous sizing compositions that are substantially insoluble in the matrix polymer. The aqueous sizing composition has one or more cross-linkable film formers, one or more organosilane coupling agents and about 3 to about 12 weight percent of the aqueous sizing composition of the epoxidized polar thermoplastic copolymer.

Abstract: Water soluble binders for can lacquers are prepared by reacting an epoxy resin (polyglycidyl ether of polyhydric phenol) with an aliphatic amino carboxylic acid, e.g., (glycine, alanine, glutamic acid), wherein at least 50% of the acid groups have been neutralized with a base (alkali metal hydroxide, tertiary amine or quaternary ammonium hydroxide.

Abstract: Novel compositions of matter comprising a water-dispersible reaction product of beta-diketones and epoxy material are hereby provided. The beta-diketones useful herein are those which enolize in amounts that render them sufficiently acidic and reactable with epoxy groups of the resin. The novel reaction products can be dispersed in water and they can be formulated optionally with curing agents. Ferrous metals treated with the compositions of this invention exhibit excellent corrosion-resistant properties.

Abstract: Resinous compositions which are the Michael adducts of primary and/or secondary amines and polymers containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties are disclosed. The compositions are depositable on substrates to form films. The films are amenable to oxidative and aminoplast cures and cure with light color. The compositions are desirable for use in cationic electrodeposition.
