EPIKURE Curing Agent 3502 is a reaction product of ethylenediamine and methyl isobutyl ketone. It is a low viscosity ketimine curing agent suitable for low-volatility coatings. Its features include low viscosity, extending the pot life of high solids coatings and adhesives, and requiring general application equipment for systems using EPIKURE Curing Agent 3502. Its uses include high solids or low-volatility maintenance and marine coatings with a film thickness of 0.008–0.010 inches. It can also be used as adhesives and industrial flooring with a thickness of 0.008–0.010 inches. In addition, it can be mixed with other curing agents to reduce viscosity and extend pot life.
EPIKURE 3502 is a low‑viscosity ketimine curing agent designed for low‑volatile epoxy coatings, adhesives and industrial floorings. It offers extended pot life (7‑8 h) and can be used with standard application equipment.
