Epoxide resins containing siloxane mixtures and method for preparation thereof and use thereof

Composition comprising (A) 50 - 99.5 wt %, based on the total weight, of A, B and C of a reaction resin or reaction resin mixture that is processed into thermosetting materials, said resin or resin mixture being liquid at temperatures in the range of 15 to 100 DEG C and having an average molecular weight of 200 to 500,000 and with a sufficient number of suitable reactive groups for a curing process; (B) 0.5 - 50 wt %, relative to the total weight of A, B and C of one or more dispersed polyorganosiloxanes that are contained in the reaction resin or reaction resin mixture homogeneously in finely distributed form as polyorganosiloxane droplets with a diameter of 0.001 to 4 microns, wherein the organopolysiloxane particle is a polymer of the general formula (R3SiO1/2)W(R2SiO2/2)X.(RSiO3/2)Y.(SiO4/2)Z, where w = 0 to 20 Mol %, x = 80 to 99.9 Mol%, y = 0.5 to 10 Mol%, z = 0 to 10 Mol%; and (C) 0.1 - 50 wt %, based on the total weight of A, B and C of one or more silicone organo copolymers as dispersing agents that
