EpoxyPro EPH-200B

Balanced 2:1 Curing Agent — General-Purpose Industrial Hardener

EpoxyPro EPH-200B is a balanced-reactivity 2:1 epoxy hardener designed for reliable, versatile performance across marine, industrial, flooring, structural and casting applications.
When paired with EPR-100A, EPR-110A or EPR-150A resin, EPH-200B produces a strong, durable epoxy matrix with consistent handling properties and predictable cure behaviour.

With a pot life of 30–45 minutes at 25°C and a viscosity of 400–800 mPa, EPH-200B offers excellent working time for bonding, coating, laminating, repairs and medium-depth castings without generating excessive heat.
