▎ 摘　　要

NOVELTY - Thermosetting mass comprises: (A) at least one radically curable compound containing at least one (meth)acrylate, (B) at least one radical initiator based on a peroxo compound, where the peroxo compound comprises at least one peroxodicarbonate, (C) at least one stabilizer comprising at least one sterically hindered phenol, and (D) at least one synergist based on a carbon modification having unsaturated carbon-carbon bonds. USE - The thermosetting mass is useful as sealing, adhesive and/or casting compound for joining, casting or coating substrates (all claimed). ADVANTAGE - The mass has excellent heat-curing property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for using the masses for joining, casting or coating substrates, comprising (a) providing the mass, (b) dispensing the mass onto a first substrate. (c) selectively supplying a second substrate to the mass, (d) optionally fixing the composition by exposure to actinic radiation; and (e) heating the mass and the substrate and/or the substrate composite at 60-100° C for 5-60 minutes, with the mass curing.
