This invention relates to a hardener composition for an epoxy resin based two-pack coating formulation wherein the hardener composition comprises moieties having at least one structural element of formula > N - D1 - NH2, and moieties having at least one structural element of formula > N - D2 - NH - C(O) - Q, wherein D1 is a bivalent group, D2 is a bivalent group, and Q is a univalent group, to epoxy resin based two-pack coating formulations comprising at least one epoxy resin which is a polymer containing, on average, at least two epoxide groups per molecule, and the hardener composition, and at least one of diglycerides which are esters of glycerol with two molecules of fatty acid, monoglycerides which are esters of glycerol with one molecule of fatty acid, or glycerol, or the reaction products of at least one of diglycerides or monoglycerides or glycerol with organic compounds having at least one reactive group selected from the group consisting of acylesters, acylanhydrides, isocyanates, epoxides, cyclocarbonates, and aziridines, and to the use of these epoxy resin based two-pack coating formulations as protective coatings on metallic and mineral substrates.
本发明涉及一种用于基于环氧树脂的双组分涂料配方的固化剂组合物,其中固化剂组合物包括至少具有一个式> N - D1 - NH2的结构单元的分子,以及至少具有一个式> N - D2 - NH - C(O) - Q的结构单元的分子、其中 D1 为二价基团,D2 为二价基团,Q 为一价基团,以环氧树脂为基础的双组分涂料配方,包含至少一种环氧树脂(平均每个分子含有至少两个环氧基团的聚合物)和固化剂组合物、和至少一种二甘油酯(即甘油与两分子脂肪酸的酯)、单甘油酯(即甘油与一分子脂肪酸的酯)或甘油,或至少一种二甘油酯或单甘油酯或甘油与具有至少一个反应基团的有机化合物的反应产物,这些反应基团选自由酰酯组成的组、酰酐、异氰酸酯、环氧化物、环碳酸盐和氮丙啶组成的组中的至少一种反应基团的有机化合物的反应产物,以及将这些以环氧树脂为基础的双组分涂料配方用作金属和矿物基材的保护涂料。
