ABSTRACT:
The present invention relates to activated curing combinations for organic cationically polymerizable materials. The curing combinations are obtainable by activating a solution or a dispersion of an iron/arene salt and a polycarboxylic acid, an anhydride based on a polycarboxylic acid, or a polyisocyanate by heating or by irradiation with actinic radiation. The curable compositions containing these activated curing combinations can be used as sheathing or encapsulating materials for electronic components.
