| 摘要 |
The present invention relates to hardener compositions for epoxy resins (epoxy resin curing agent composition) comprising a mixture of crosslinking agents comprising (a) at least one polyamide functional compound, which has at least one amide function and at least one amine function per molecule, with the proviso that the polyamide (a) is obtained by the reaction of a dimer fatty acid or an alkylester of a dimer fatty acid with at least one polyamine, and (b) at least one phenalkamine compound, which is the condensation product of an alkyl phenol, formaldehyde and one or more at least dibasic polyamine, provided that the dimer fatty acid building block used to obtain the polyamide functional compound (a) comprises monomeric fatty acid in an amount of 20-60% by weight, based on the total amount of the dimer fatty acid.
