Abstract:
A cationically hardenable composition comprising, in combination:(A) from 5 to 90 parts by mass of at least one at least difunctional cationically polymerizable compound; (B) from 0.01 to 5 parts by mass of a diaryliodonium salt as a photo-initiator for cationic hardening; (C) from 0.1 to 70 parts by mass of at least one compound containing a hydroxyl group and having a molar mass of from 150 to 10,000 g/mol and hydroxy-equivalent masses of from 50 to 5,000 g/mol; (D) from 0.01 to 10 parts by mass of a compound releasing radicals when heated and having a half-life of one hour at a temperature of less than 100Â° C.; (E) from 0.001 to 10 parts by mass of a photo-initiator forming radicals or of a photo-sensitizing agent for diaryliodonium salts; and (F) from 0 to 60 parts by mass of modifiers, selected from the group consisting of a filler, a dye, a pigment, a stabilizer, an accelerator, a retardant, an initiator, a flow promoter, a thixotropic agent, a diluent, a polymeric thickening agent, and a mixture thereof, with the sum of all the parts by mass amounting to 100 and all the constituents (A) to (F) of the cationically hardenable composition being present in the form of a single-component mixture capable of being stored in a stable manner and with the cationically hardenable composition being completely hardenable when light-initiated and/or heat-initiated.
