Abstract:
The present invention relates to hardeners for epoxy resins, which contain secondary aliphatic and primary aromatic amino groups. They harden surprisingly quickly together with epoxy resins even under cold and humid conditions and without blushing effects to give films with a high degree of hardness. They are especially suitable for coatings with high resistance requirements.
