The invention relates to a dual-curing solvent-free single-component mass for the bonding, molding, sealing and coating of substrates, in particular of electronic components. The mass comprises an at least bifunctional epoxy-containing compound; a hybrid compound carrying at least one isocyanate group and, at the same time, at least one radically polymerizable group; a latent curing agent based on nitrogen compounds suitable for crosslinking the epoxy-containing compound by addition reaction; a photoinitiator capable of forming radicals when irradiated with light, and optionally other additives. The mass is characterized in that it is surface dry after light curing by means of radical photopolymerization.

Dual-curing solvent-free single-component masses and their use

We propose a thermosetting solvent-free single-component composition having a storage stability at room temperature of at least 2 weeks, consisting of

Thermosetting solvent-free single-component compositions and their use

Cationically hardening masses are described, which can be stored and handled as single-component masses and comprise at least one difunctional cationically polymerizable compound; a photo-initiator for the cationic hardening based upon diaryliodonium salts; at least one compound containing an hydroxyl group; a compound releasing radicals when heated and having a half-life of one hour at a temperature of less than 100&deg; C.; a photo-initiator forming radicals or of a photo-sensitizing agent for diaryliodonium salts; and from 0 to 60 parts by mass of modifier. The compounds are used for bonding, casting, sealing and coating of substrates.
