Abstract
Bulk-modified potting composition based on a curable epoxy resin or on a mixture of these resins, where the resin or the mixture is composed of an epoxy resin, a hardener, where appropriate an accelerator, and also other additives, such as fillers, flexibilizers, and colorants, which potting composition (a) comprises a three-dimensionally crosslinked polysiloxane in disperse form and with a particle size in the range from 0.02 μm to 50 μm, which, where appropriate, has reactive groups which can react chemically with the epoxy resin and/or the hardener, (b) a selected linear or branched siloxane compound which has reactive groups which can react chemically with the epoxy resin and/or the hardener, and also, where appropriate, (c) a low-molecular-weight oligomeric siloxane compound, the use of the potting composition as an engineering material or as an insulating material, and the moldings and insulation produced therefrom.
