Abstract: Co-condensates are prepared by condensing from 0.8 to 2.0 moles of butyraldehyde with 1 mole of a phenol at from 80.degree. to 220.degree. C. with the addition, before, during or after the condensation, of from 5 to 50% by weight, based on the mixture of phenol and butyraldehyde, of one or more thermoplastics containing functional groups, which reacts with phenol, butyraldehyde or the phenol-butyraldehyde resin under the condensation conditions. The co-condensates are used as hot-melt adhesives and as binders for nonwovens.

Abstract: Thermosetting powder coatings comprising reactive polymers containing reactive carboxyl, hydroxyl, and/or amide groups and adapted to be cross-linked with aminoplast resins are substantially improved by the inclusion of at least about 0.25% by weight of a heat curing catalyst. The catalyst is an amine salt of cyclohexyl sulfamic acid.

Abstract: A method for preparing a furan-epoxy powder-like binder which comprises interaction of an epoxy diane resin with a nitrogen-containing furan monomer, such as furfuramide or 3-methyl-5-furylpyrazoline at a temperature ranging from 140.degree. to 160.degree. C. at a ratio of the nitrogen-containing furan monomer to the epoxy diane resin equal to 0.2:5 to 3.4:5 expressed in parts by weight. The process may be performed in the presence of trifurylborate at the weight ratio thereof to the epoxy diane resin equal to 0.05:5 to 0.6:5 expressed in parts by weight. The resulting product is cooled to a temperature of not more than 30.degree. C. and then disintegrated to a powder-like state. The furane epoxy binder prepared by the method according to the present invention does not get clogged for 45 days and may be stored for long periods of up to 6 months without any changes in its initial properties. Vicat deformation heat-resistance of the polymeric material produced with the use of said binder is as high as 230.

Abstract: Epoxy-resin powder primer compositions for metal substrates which have good flow, corrosion resistance, and adhesion to lacquer overcoats are provided by blending two epichlorohydrin-bisphenol-A epoxy resins with a curing agent. One of the epoxy resins can be extended with phenol to increase its flow properties. The curing agent is a hydroxy-containing mixed aromatic-aliphatic polyether resin.

Abstract: A powder coating composition for forming multi layer coatings comprising:(1) at least one of finely divided thermosetting addition copolymers having a glass transition temperature of 35.degree. to 75.degree. C. and comprising as comonomers a wt. % of a hardness imparting monomer and b wt. % of a softness imparting monomer based on the copolymer wherein a+b.ltoreq.60, b.ltoreq.a and b.ltoreq.20, and(2) at least one of finely divided thermosetting resinous materials having incompatibility or low compatibility with the copolymer and a substantially greater surface tension than the copolymer when melted at the same temperature and substantially differing from the copolymer in composite parameter.

Abstract: A moulding composition consisting of an epoxy resin adduct of a low molecular diglycidyl ether of bisphenols and an aromatic diamine together with a filler, an accelerator, and an aromatic polyol as hardener. Mouldings having excellent resistance to cracking can be obtained from this moulding composition.

Abstract: Free flowing resin powder which upon striking a heated article fuses, flows and hardens to provide a protective coating, which powder consists of a mixture of rough and rounded particles, the rough particles having a granular appearance as a result of being pulverized and the rounded particles having smooth, glossy, spheroidized surfaces as a result of being briefly heated to a temperature above the softening point. Preferably each particle of the powder is a blend of thermosetting resin and curing agent.

Abstract: A powder coating composition useful for coating metal substrates to provide a low gloss finish; the powder particles are a blend of(a) a polyester or a blend of polyesters,(b) an epoxy resin,(c) triglycidyl isocyanurate,(d) calcium carbonate pigment and(e) finely divided polypropylene particles;The composition is particularly useful for providing the interior of automobiles, station wagons and trucks with a low gloss finish.

Abstract: The powdery coating composition of the present invention comprises:(i) 10 to 40% by weight of a solid cross-linking agent prepared by heating polyester and alkoxyaminotriazine, and(ii) 90 to 60% by weight of a base resin.An object of the present invention is to provide a powdery coating composition which will not pose any environmental pollution and has an outstanding property against bubbling.The above object can be fulfilled by using the solid cross-linking agent in combination with a base resin.

Abstract: Composition especially useful as an interlining adhesive comprising a blend of a polyester and a polyamide. The polyester is derived from at least about 40 moles percent terephthalic acid, has a melting point of between about 90.degree. C. and about 140.degree. C. and a heat of fusion of from about 0.1 to about 10 calories per gram. The polyamide has a melting point of between about 50.degree. C. and about 200.degree. C. Such a composition may be melt blended and cryogenically ground to a fine powder size and is resistant to blocking.
