Abstract
A composition containing calcium nitrate, at least one epoxy resin and at least one amine of formula (I). The composition allows the manufacture of low-emission epoxy-resin coatings that have good workability and that cure particularly rapidly in cold and damp conditions, without blushing-induced surface defects, thus achieving coatings of in particular high mechanical quality, with a minimal tendency to yellowing.
