Abstract
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.
Claims19
A curing agent composition comprising (a) at least one benzylated polyalkylene polyamine having at least three nitrogen atoms, at least three active amine hydrogen atoms and at least one substituted or unsubstituted benzyl group and (b) at least one multifunctional amine having 3 or more active amine hydrogens;
- wherein the at least one benzylated polyalkylene polyamine comprises the reductive amination product of at least one substituted or unsubstituted benzaldehyde compound with at least one polyalkylene polyamine;
- and wherein the at least one multifunctional amine comprises at least one member selected from the group consisting of ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA), tetraethylenepentamine (TEPA), pentaethylenehexamine (PEHA), propylenediamine, dipropylenetriamine, tripropylenetetramine, N-3-aminopropyl ethylenediamine (Am3), N,N′-bis(3-aminopropyl) ethylenediamine (Am4), N,N,N′-tris(3-aminopropyl) ethylenediamine (Am5);
- N-3-aminopropyl-1,3-diaminopropane, N,N′-bis(3-aminopropyl)-1,3-diaminopropane, N,N,N′-tris(3-aminopropyl)-1,3-diaminopropane, and any combination thereof.
A curing agent composition comprising (a) an amine-epoxide adduct and (b) at least one multifunctional amine having 3 or more active amine hydrogens;
- wherein the amine-epoxide adduct comprises a reaction product of a novolac epoxide resin and at least one benzylated polyalkylene polyamine having at least three nitrogen atoms, at least three active amine hydrogens and at least one substituted or unsubstituted benzyl group;
- wherein the at least one benzylated polyalkylene polyamine comprises the reductive amination product of at least one substituted or unsubstituted benzaldehyde compound with at least one polyalkylene polyamine;
- and wherein the at least one polyalkylene polyamine compound comprises at least one of diethylenetriamine and triethylenetetramine.
An amine-epoxy composition comprising the reaction product of:
- A) a curing agent composition comprising the contact product of:
- at least one benzylated polyalkylene polyamine having at least three nitrogen atoms, at least three active amine hydrogen atoms and at least one substituted or unsubstituted benzyl group;
- and at least one multifunctional amine comprising at least one member selected from the group consisting of ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA), tetraethylenepentamine (TEPA), pentaethylenehexamine (PEHA), propylenediamine, dipropylenetriamine, tripropylenetetramine, N-3-aminopropyl ethylenediamine (Am3), N,N′-bis(3-aminopropyl) ethylenediamine (Am4), N,N,N′-tris(3-aminopropyl) ethylenediamine (Am5);
- N-3-aminopropyl-113-diaminopropane, NIN′-bis(3-aminopropyl)-1,3-diaminopropane, N,N,N′-tris(3-aminopropyl)-1,3-diaminopropanel, and any combination thereof;
- and
- B) an epoxy composition comprising at least one multifunctional epoxy resin;
- wherein the at least one benzylated polyalkylene polyamine comprises the reductive amination product of at least one substituted or unsubstituted benzaldehyde compound with at least one polyalkylene polyamine.
