ARADUR® 3951

ARADUR® 3951 is a water-dilutable multi-purpose polyamide curing agent. It is specially designed for the formulation of water-dilutable epoxy resins. This product is used to formulate two-component metal anticorrosion primers, such as zinc-rich primers and primer-based coatings used for industrial corrosion protection, ships, and freight containers. When combined with a suitable epoxy emulsion, it can provide low VOC, fast drying, and excellent corrosion protection.
