    • Thermosetting powder paint composition and polyester resin which can be used for its manufacture.The invention relates to thermosetting powder paint compositions based on carboxyl group-containing polyester resins as well as polyepoxides and/or β-hydroxyalkylamides as curing agents.The polyester resins have an acid number of 10 to 100 and a hydroxyl number of at most 15 mg KOH/g polyester resin and consist of at least 50 mol %, with respect to the totality of the dicarboxylic acids contained, of units of isophthalic acid, and of at least 50 mol %, with respect to the totality of the diols contained, of units of neopentyl glycol, and contain a maximum of 10 mol %, with respect to the totality of all dicarboxylic acids and diols, of monomers having a functionality of 3 or greater.Through the addition of 0.05 to 5 wt. % of a heterocyclic polycarboxylic acid into the powder paint mixture, preferably through melting of this acid into the polyester resin used for the manufacture of the powder paint, highly weather-resistant powder coatings with outstanding mechanical properties and surface appearance can be achieved.
    • 热固性粉末涂料组合物和可用于其制造的聚酯树脂。 本发明涉及基于含羧基的聚酯树脂以及聚环氧化物和/或β-羟基烷基酰胺作为固化剂的热固性粉末涂料组合物。 聚酯树脂的酸值为10〜100,羟值为15mgKOH / g以下的聚酯树脂,相对于所含的二羧酸的总量,至少为50mol%的间苯二甲酸单元 ,相对于所包含的二醇的总量,至少为50摩尔%,相对于所有二羧酸和二醇的总量,最多含有10摩尔%的新戊二醇单元 3或更大的功能。 通过加入0.05〜5wt。 %的杂环多元羧酸进入粉末涂料混合物中,优选通过将该酸熔化成用于制造粉末涂料的聚酯树脂,可以实现具有出色的机械性能和表面外观的高耐候性粉末涂料。
