| Résumé : |
Two new waterborne amine adduct hardeners with different reactivity (high/low) have been developed. By mixing the two curing agents, it is possible to tune the reactivity of the formulation. The influence of the reaction temperature and the stoichiometry on the potlife and on other paint properties is discussed. The potlife is determined by the MFT method. The hardeners contain no VOC, and can be used with both liquid epoxy resins and solid epoxy resin emulsions. Special features, like early moisture resistance and the yellowing tendency of coatings are high-lighted. Several starting formulations, e.g., highgloss topcoats, concrete primers, and matt floorings, are presented. This paper helps to demonstrate that waterborne epoxy systems have reached a level of performance that make them adequate substitutes for conventional formulations in many applications. |
