Properties:
After the two components have been mixed, UHU plus sofortfest hardens to form a duroplastic synthetic resin. The
parts to be assembled usually need to be fixed under pressure. It is not necessary to apply extreme pressure.
Hardening takes place by evaporation. At temperatures below room temperature, the hardening process takes
somewhat longer.
