Abstract
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.
