  • Patent number: 11680132
    Abstract: A curing agent for epoxy resins has N-benzylethane-1,2-diamine and N,N?-dibenzylethane-1,2-diamine in a weight ratio in the range from 65/35 to 95/5. The curing agent is easy to prepare, thins epoxy resins particularly well, and enables low-emission epoxy resin products that have good workability and a long pot-life, cure reliably and surprisingly fast and can be walked on after a short time, in particular even in cold conditions. Coatings of particularly high mechanical grade, with a high surface quality and a minimal tendency to yellowing, can thus be produced. Epoxy resins of this type are particularly suitable for coating floors.
