Abstract: Powdered coating agents contains, as binder forming components, a mixture of (A) >=1 OH-gp. contg. resin, with an OH value of 30-200, pref. 60-120, a glass temp. of 35-95 degrees C, pref. 45-70 degrees C and an average mol. wt. of 1000-10,000, pref. 2000-70000, and (B) >=1 di- or polyacyl isocyanate masked by an aliphatic monoalcohol opt. contg. ether gp(s). The compsn. can be stoved at 150-200 degrees C. pref. 160-175 degrees C, for 5-40, pref. 10-30 mins, to give cross-linked elastic, solvent-stable and corrosion-protecting coatings having good flow properties and high polish on metals, glass, ceramics, concrete, plastics, wood, etc. The decompsn. products produced are relatively free from environmental problems.

Abstract: Stoving lacquers consist of (A) polymers contg. OH gps. (B) a cross-linking component and (C) additives e.g. solvents, pigments, flow agents and catalysts, in which (B) is a cpd. with at least 2 oxazolone-(5) gps. Cross-linking is by addn. only no volatile substances e.g. amines, HCHO or alcohols being released to pollute the atoms. The compsns. are suitable for u se in high solids systems or powder coating, and give satisfactory alkali and water resistance. Smooth glossy coatings are obtd. with excellent mechanical properties.

Abstract: Binders for stoving finishes contg. a copolymer of average mol. wt. 1000-10000 derived from (A) 10-30 wt.% of an olefinically unsatd. cpd. which is an adduct of Vi isocyanate and an end-capping component having a CH-, OH-, or NH-acidic gp., (B) 0-25 wt.% of an olefinically unsatd. cpd. having NCO-reactive H atoms, (C) 20-70 Wt.% of an acrylic or methacrylic ester of a 1-18C monohydric alcohol and (D) 0-50 wt.% of other olefinically unsatd. cpds. Prods. are easily prepd. from readily available raw matls. and contain well-defined amts. of capped -NCO gps. so that they are equally suitable for one-or 2-component systems.

Abstract: A heat-hardenable coating compsn. contains as binder a mixt. of (A) 94-60 (90-70) pts. wt. of a copolymer of (a) 25-70 (45-65) wt. % is not 1 vinyl-aromatic and/or methyl methacrylate and/or (meth)acrylonitrile, (b) 20-60 (30-55) wt. % is not 1 ester of a 3-5C olefinically unsatd. carboxylic acid with 1-18C alkanol, and (c) 3-25 (5-15) wt. % of an alpha, beta-ethylenically unsatd. nomo- or di-carboxylic acid, with melt viscosity fo 500-10,000 Pas at 120 degrees C and (B) 6-40 pts. wt. of a cpd. with 2 epoxy gps. of formula:- where R is -CH2- , H, (cyclo)alkyl, aryl, acyl or a residue of formula:- and n = 1-10. The compsn. may be used as a powder coating or a solvent lacquer. It can be applied to substrate, e.g. metals by electrostatic deposition and baked at 130-220 degrees (140-180 degrees C). The coating is hard, elastic, glossy, fast to light and to weather; it does not become yellow. The compsn. is brittle and easily ground at room temp. The raw materials are cheap and easily available. The powder compsn. evolves little volatile matter on baking.
