EPIKURE™ Curing Agent 8537-WY-60


EPIKURE™ Curing Agent 8537-WY-60 is a water reducible amine adduct supplied at 60 percent solids in water. When combined with suitable epoxy resins, waterborne coatings may be formulated to meet a variety of end use requirements.


For spray applications, additional reduction with water may be desired, although it is not necessary because of the excellent atomization properties of these coatings. Reasonably high film build coatings may be achieved with spray application. A finishing system providing a final film build averaging 7 mils would consist of a primer (2.5 mils), an intermediate coat (3.0 mils) and a gloss enamel (1.5 mils), all based on EPIKURE Curing Agent 8537-WY-60.
