Curing agents for epoxy resins |
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 obtainable 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 ore more at least difunctional amines,
with the proviso that the dimer fatty acid building block used to obtain the polyamide functional compound (a) comprises the monomeric fatty acid building bock in an amount of 20 - 60 % by weigth (based on the total amount of the dimer fatty acid).
