The present invention relates to aromatic aldimines, which are based on primary aromatic polyamines, which are solid at room temperature and liquid at room temperature and which have the lowest possible viscosity, hydrolyze with little odor, and can be used as blocked amines in curable compositions, in particular in compositions having one-component and two-component isocyanate groups. Said compositions have a relatively long open time, but cure surprisingly rapidly, said curing occurring without strong odor formation and without bubbling. In addition, the compositions have outstanding mechanical properties after curing, in particular high strength with high ductility, and good resistance to heat and moisture. |
