A curing agent composition including at least one benzylated polyamine compound. The benzylated polyamine compound is a reaction product of a benzaldehyde compound or benzyl halide compound and a polyamine according to the following formula:H2N&#x2014;CH2-A-CH2-NH2where A is a phenylene group or a cyclohexylene group. A method for making the curing agent composition and an amine-epoxy composition are also disclosed.

Benzylated polyamine curing agents

The present invention provides curing agent compositions comprising alkylated polyalkylene polyamine compounds. Amine-epoxy compositions and articles produced from these amine-epoxy compositions are also disclosed.

Alkylated polyalkylene polyamines and uses thereof

The present disclosure provides polyamides and amidoamine curing agents including the reaction product of (1) a modified amine component comprising at least one multifunctional amine of structure 1: wherein Ris selected from C-Clinear, cyclic, and branched alkyl, alkenyl, and alkaryl groups; Rand Rare hydrogen, Ris Ror hydrogen, X, Y, and Z are independently selected from C-Calkylene, hexylene and cycloalkylene groups, n=0, 1, 2, 3, 4, 5, 6, or 7; and (2) a fatty acid component. Exemplary fatty acid components include at least one of monomer fatty acids, dimer fatty acids, trimer fatty acids, polymer fatty acids, esters of monomer, dimer, trimer, and polymer fatty acids and combinations thereof. The method for making the curing agents and articles formed therefrom are also disclosed.

Polyamides and amidoamines from selectively modified amine amines

The present invention provides epoxy curing agent compositions comprising benzylated aminopropylated alkylenediamine compounds. Amine-epoxy compositions and articles produced from these amine-epoxy compositions are also disclosed.

Benzylated aminopropylated alkylenediamines and uses thereof

The present invention provides epoxy curing agent compositions comprising alkylated aminopropylated alkylenediamine compounds. Amine-epoxy compositions and articles produced from these amine-epoxy compositions are also disclosed.

Alkylated aminopropylated ethylenediamines and uses thereof

The present invention provides curing agent compositions comprising benzylated polyalkylene polyamine compounds. Amine-epoxy compositions and articles produced from these amine-epoxy compositions are also disclosed.
