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 &#x3e;N-D1-NH2, and moieties having at least one structural element of formula &#x3e;N-D2-NH&#x2014;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.

Hardener composition for epoxy resin based coating compositions, process for their preparation and use thereof

Urethane modified water-reducible alkyd resins ABCD, comprising moieties derived from polyhydric alcohols A, modified fatty acids B made h&#x3b3; grafting olefinically unsaturated carboxylic acids B2 onto fatty acids B1, ungrafted fatty acids C and polyfunctional isocyanates D, a process for their production, and a method of use thereof in coating binders

Urethane modified water-reducible alkyd resins

Water dilutable amine curing agents for aqueous epoxy resin dispersions, comprising a combination of an epoxide-amine adduct with an emulsifier, the epoxide-amine adduct being obtainable by reacting a polyepoxide with a reaction product of an amine and an epoxide component or an amine and subsequent reaction with an epoxide component, the amount of amine being chosen such that the number of nitrogen-attached hydrogen atoms the number of epoxide groups by a factor of from 2 to 10, and the emulsifier being obtainable by reacting diepoxides or polyepoxides with compounds that are at least difunctional with respect to epoxides, optionally with compounds D that are monofunctional with respect to epoxides, and with amines G which contain at least one tertiary and at least one primary or at least two secondary amino group(s).
