Abstract
An amine of formula (I) which is particularly suitable for use as a curing agent for epoxy resins. The amine of formula (I) is devoid of non-incorporable toxic phenols, and is low-viscosity and pale in color. It allows the production of easily-workable, low-emission or emission-free epoxy resin products which cure rapidly even at relatively low ambient temperatures thus obtaining a high degree of hardness and a nice surface with hardly any yellowing. This is particularly suited to use in floor or top coatings.
