Abstract

The present invention relates to curing agents for epoxy resins, containing at least one adduct of trimethylhexamethylenediamine and cresyl glycidyl ether. The curing agent has a low viscosity and cures quickly together with epoxy resins even in moist, cold conditions and without blushing to form films with a high hardness and surface quality, which scarcely undergo yellowing upon exposure to light. It is particularly suited for low-emission room temperature-curing coatings.
