EpoxyPro EPH-210B Medium Cure Hardener 2:1

EpoxyPro EPH-210B

Medium-Cure 2:1 Hardener — High-Viscosity Marine, Electrical & Industrial Grade

EpoxyPro EPH-210B is a high-viscosity, medium-reactivity 2:1 epoxy hardener designed for marine laminating, electrical potting, industrial bonding, structural repairs and medium-depth casting.

With a viscosity of 12,000–18,000 mPa @ 25°C and a pot life of 60–80 minutes, EPH-110B provides excellent handling time for larger builds, laminating, assembly work, potting and repairs.

When combined with EPR-100A, EPR-110A or EPR-150A, EPH-210B produces a durable epoxy with strong adhesion, moisture resistance and smooth final cure.
