The at least one curing agent is selected from 4,4'-methylene bis(2,6-diethyl-3-chloroaniline), 4,4'-methylene bis(2-chloroaniline), methylene bis(2-ethyl-6-methylaniline), 4,4'-methylene bis(2- ethylbenzeneamine), methylene bis(2,3-dichloroaniline), 4,4'- methylenedianiline, 3,5-dimethylthiotoluene-2,4-diamine, 3,5- dimethylthiotoluene-2,6-diamine, 3,5-diethyltoluene-2,4-diamine, 3,5- diethyltoluene-2,6-diamine, polytetramethylene oxide di-p-aminobenzoate, poly(tetramethylene/3-methyl tetramethylene ether)glycol bis(4- aminobenzoate), trimethylene bis(4-aminobenzoate) and isobutyl 4-chloro- 3,5-diaminobenzoate.
