ARADUR® 3986

ARADUR® 3986 epoxy curing agent is an amine hardener specially formulated for water-dilutable epoxy resin systems. This product is free of volatile amines and solvents. It was developed for the formulation of anticorrosive primers that is using waterborne epoxy resins such as ARALDITE® PZ 3961-1 epoxy resin and other water-based coatings. ARADUR® 3986 epoxy curing agent provides a visible end of the usable life (indicated by viscosity increase) and the desired combination of fast set-to-touch times and long pot life with both modified and unmodified liquid epoxy resins, such as ARALDITE® GY 6010 or ARALDITE® GY 9615.

Application Information

ARADUR® 3986 Epoxy Curing Agent is designed for heavy-duty corrosion resistance comparable to solvent-based epoxy systems, and with several advantages: low VOC, low odor and fast dry properties. It can be used with both liquid epoxy resins and waterborne solid epoxy resin dispersions for the formulation of primers and direct-to- metal applications. It offers long pot life, excellent adhesion, and good impact resistance. It can also be formulated for a visible end-of-pot life.
