Coating industry across all markets from construction to marine to electronics is constantly facing the challenges from regulatory agencies and consumers. These challenges include meeting more stringent emission requirement and fulfilling the need to reduce process time in order to improve productivity and costs while maintaining high coating performance. Technology advancements equipped the industry with new waterborne epoxy systems that deliver fast cure speed, improved coating robustness and better aesthetics over the service life. Thanks to the low volatile organic content (VOC) and excellent coating properties, waterborne epoxy coatings have become a commercially important technology and gained wide acceptance as environmentally friendly alternatives for solvent borne and solvent free epoxy systems.
This paper will highlight the development of a new waterborne epoxy curing agent based on a novel amine technology. The paper will also discuss the key advantages of the new waterborne epoxy system for civil engineering application. This new system provides an extremely fast cure speed even under adverse condition such as low temperature and high humidity, and superior adhesion to substrates when used as a primer, in particularly on damp concrete. It also provides excellent surface aesthetics when used as a topcoat. This fast cure system enables coating formulators to design new coating concepts, such as a 1-day floor system, consisting of a primer and topcoat that could be applied on the same day and deliver walk-on readiness the next morning.
