    Abstract: PROBLEM TO BE SOLVED: To obtain a coating composition improved in stability in use in a direct gas combustion furnace and/or an oil combustion furnace, by adding a compound (stabilizer) having a specified structure to a powder coating based on a carboxyl-functional polyester and a β-hydroxyalkylamide. SOLUTION: This composition comprises a carboxyl-functional polyester formed by the condensation reaction of aliphatic and/or alicyclic polyols with aliphatic and/or alicyclic and/or aromatic polycarboxylic acids and an acid anhydride and having a Tg of 30-80 deg.C and an acid value of about 20-100mgKOH/ g, 0.6-1.6 equivalent, per equivalent of the carboxylic acid, of a β- hydroxylalkylamide and 0.001-10wt.% at least one compound represented by formula I (wherein R1 is OH, a 1-10C alkyl or a halogen), formula II, formula III, or formula IV (wherein R1 to R10 are each OH, or one of them is OR11 , and the rest are each H, a 1-10C alkyl or a halogen).

    Abstract: Heat-cured coating powder containing hydroquinone or mono-alkylated hydroquinone derivatives of benzene, naphthalene, anthracene or phenanthrene in addition to carboxy-functional polyesters, Bisphenol A epoxy resins and optionally pigments and/or other additives. Heat-cured coating materials comprising: (A) a carboxy-functional polyester with a Tg of 30-80 degrees C and an acid number of 20-100 mg KOH/g, obtained by condensation of aliphatic and/or cycloaliphatic polyols with aliphatic and/or cycloaliphatic and/or aromatic polycarboxylic acids or anhydrides; (B) a Bisphenol A/epichlorhydrin-based epoxy resin in an equivalent ratio of epoxide/carboxylic acid = 0.6-1.2; (C) compound(s) of formula (I)-(X) and optionally pigments and/or fillers and/or thermal stabilizers, preferably phosphites and/or tribo-additives and/or other additives such as flow improvers and degassing agents. R = optionally branched 1-10 C alkyl. An Independent claim is also included for a process for the production of coating powders by melt-compounding the above components at 60-140 degrees C in an extruder, cooling the extruded product, milling and sieving to a particle size of less than 90 microns.
