Ancamine® 2489 curing agent is a low-color cycloaliphatic amine adduct intended for use with liquid epoxy resins. It has a very low viscosity which imparts low mixed viscosity in epoxy systems and reduced need for diluents. Ancamine® 2489 curing agent gives very rapid development of physical properties at ambient and low temperatures for a fast return to service, while maintaining longer working life than conventional fast cure hardeners. It yields formulations with good waterspot resistance, resistance to amine blush and chemical resistance. Ancamine® 2489 curing agent utilizes state-of-the-art adduct technology to provide a favorable combination of properties for formulating a variety of civil engineering and coating materials.
