ARADUR 3290 is designed primarily for civil-engineering epoxy applications.

ARADUR 3290 reacts through its active amine hydrogens with epoxy functional groups.
ARADUR 3290 forms a crosslinked thermoset structure during the curing reaction.
ARADUR 3290 provides rapid cure development because of its high amine functionality.
