Compositions and curing agents comprising a benzylated Mannich base composition. The benzylated Mannich base composition includes a reaction product of (a) a substituted phenolic compound having at least one substituent of formula (I):
wherein R
1
is each independently a linear or branched alkyl group having 1 to 4 carbon atoms, and R
2
is hydrogen, methyl, ethyl or phenyl, with (b) a benzylated polyalkylene polyamine (II):
wherein R
A
is substituted or unsubstituted benzyl; R
B
is each independently R
