Abstract
Disclosed herein are tricyclic and pentacyclic polyamines having a secondary or tertiary amine group on an amine functional substituent and at least one primary amine group on each of two amine functional substituents in the molecule. These compounds function excellently as non-visably carbonating epoxy curing agents and in addition unlike most other amines exhibit a mild amine odor.
