ARADUR® 70

ARADUR® 70 can be formulated with modified or unmodified bisphenol A and bisphenol F-based liquid epoxy resins. It is suitable for the formulation of flexible binder systems, impact-resistant coatings, and sealers. Unlike externally plasticized systems, the flexibility of these systems is permanent and retained at low temperatures. ARADUR® 70 is a polyether urethane amine curing agent.
