How can I formulate a low-viscosity epoxy flooring system with fast cure for a quick return to service while still giving applicators reasonable working time?

Traditionally, formulators of epoxy flooring systems have had to choose between fast cure and a long working life, a result of traditional curing agent limitations. Additionally, the need for fast cure often has resulted in a sacrifice of final system appearance and performance properties.
Ancamine® 2489 curing agent can be used to formulate epoxy flooring and coating systems that have both rapid cure and a long working life, when compared to conventional fast cure hardeners. It gives fast hardness development, even at low temperatures, which allows flooring projects to be completed and returned to service quickly. This product is a low-color, cycloaliphatic amine adduct that imparts very low mixed viscosity in epoxy systems, reducing the need for diluents, improving handling properties, and/or allowing higher filler loading. Ancamine 2489 also offers lower cost in use and yields formulations with very good resistance to amine blush and waterspotting.
