The present invention relates to a process for the production of a ready-to-use epoxy composition having a filler content of at least 55 vol.-%, relative to the complete ready-to-use epoxy composition, which comprises:
providing a liquid A, which comprises at least one epoxy resin,providing a liquid B, which comprises at least one curing agent,providing a solid component C, which comprises at least one filler,wherein in a first step one of the liquids A or B is filled in a mixing container,in a second step the solid component C is deposited on top of the liquid in the mixing container,in a third step the remaining liquid A or B is deposited on top of the solid component C, andin a fourth step the components are mixed to obtain the ready-to-use epoxy composition. |

1. Process for the production of a ready-to-use epoxy composition having a filler content of at least 55 vol.-%, relative to the complete ready-to-use epoxy composition, which comprises:
providing a liquid A, which comprises at least one epoxy resin, providing a liquid B, which comprises at least one curing agent, providing a solid component C, which comprises at least one filler selected from the group consisting of ferrites, aluminum oxide, magnesium oxide, zinc oxide, titanium oxide, silicon oxide, aluminum hydroxide, magnesium hydroxide, silicon nitride, aluminum nitride, boron nitride, silicon carbide, aluminum, copper, graphite, nickel and silver, wherein in a first step one of the liquids A or B is filled in a mixing container, in a second step the solid component C is deposited on top of the liquid in the mixing container, in a third step the remaining liquid A or B is deposited on top of the solid component C, whereby liquid A, liquid B and solid composition C form phases which are layered on top of each other with distinct phase borders, the solid composition C phase being intermediate between the liquid A phase and the liquid B phase, and in a fourth step the components are mixed to obtain the ready-to-use epoxy composition. |
