ABSTRACT:
Curing components containing amino groups for curing epoxy resins are obtained by the reaction of alkylated polyhydroxy aromatics (A) with polyamines (B) and aldehydes (C) by the mechanism of the Mannich reaction. The preparation of curable mixtures and varnish formulations is also disclosed. The curing components and curable mixtures can also be employed at a low temperature.
