The present invention relates to a new structural class of phenalkamines, curing agent compositions comprising the phenalkamines, their use, as well as and methods of producing such phenalkamines and compositions. The phenalkamines of the present invention can be prepared by reacting cardanol with an aldehyde compound and triaminononane. These curing-agent compositions may be used to cure, harden, and/or crosslink an epoxy resin. The curing-agent compositions of this invention are of low viscosity and can be used neat or dissolved in a minimum amount of an organic solvent or diluent to effect cure of epoxy resins.
