Patent ID: 8067093

Claim:
An amine-functional compound that is suitable to use as a curing agent for epoxy-functional compounds, obtained by: reacting 40-90 mol % of a first reactant with 5-50 mol % of a second reactant to form an amide; and reacting the amide with 5-55 mol % of a third reactant; wherein the first reactant is at least one polyamine having 2 or more —NH or —NH 2 groups selected from the group consisting of ethylene diamine; 1,3 propane diamine; 2,2-dimethyl-1,3-propane diamine; 1,4-butane diamine; 2,2,4-trimethyl hexamethylene diamine; 1,3-pentane diamine; 2-methyl-1,5-pentane diamine; diethylene triamine; triethylene tetramine; tetraethylene pentamine; pentaethylene hexamine; piperazine; aminoethyl piperazine; m-xylylene diamine; 1,3-bis-(aminomethyl) cyclohexylamine; isophorone diamine; and 4,4′-methylene bis cyclohexylamine; wherein the second reactant is at least one α-β unsaturated acid, at least one α-β unsaturated ester or a combination thereof; wherein the third reactant is at least one mono-functional epoxy compound containing one epoxy group per molecule; and wherein the mol % values are based on the combined molar amounts of each reactant.
