Abstract
The present invention relates to a curable composition which comprises epoxy resin, epoxy-group-bearing reactive diluent and the hardener 2,2′,6,6′-tetramethyl-4,4′-methylenebis(cyclohexylamine), curing thereof, and the cured epoxy resin obtainable therefrom, and the use of 2,2′,6,6′-tetramethyl-4,4′-methylenebis(cyclohexylamine) as a hardener for epoxy resins in curable compositions with epoxy-group-bearing reactive diluent.
Claims15
A curable composition, comprising:
- an epoxy resin;
- an epoxy-group-bearing reactive diluent;
- and
- 2,2′,6,6′-tetramethyl-4,4′-methylenebis(cyclohexylamine),
- wherein said curable composition is free from aromatic diamines.
A process for hardening an epoxy resin, the process comprising adding 2,2′,6,6′-tetramethyl-4,440 - methylenebis(cyclohexylamine) in a curable composition with one or more epoxy-group-bearing reactive diluents.
