Lanthanide triflates, a new class of cationic initiators, have been tested as curing agents for cycloaliphatic epoxy resins. Several metal salts in various proportions have been used. The triflate salts were compared with the conventional BF 3 MEA system. The processes have been kinetically evaluated by isoconversional analysis, time and temperature predictions have been made. Their mechanical properties have been evaluated by dynamic mechanical thermal analysis (DMTA).
