    Abstract: PROBLEM TO BE SOLVED: To provide a thermally conductive silicone grease composition excellent in both thermal conductivity and shear resistance. SOLUTION: The thermally conductive silicone grease composition includes at least components (A)-(C). The aggregate amount of the component (B) and (C) accounts for 500-2,000 pts.mass based on 100 pts.mass of the component (A). Component (C)/(component (B)+component (C)) representing a mixed ratio of the component (B) and the component (C) is 0.05-0.5 by mass. Component (A): Organopolysiloxane having a thixotropy index α as defined by η 1 /η 2 of 1.03-1.70, a viscosity at 25°C of 10-1,000,000 mPa s, wherein η 1 is a viscosity as determined at 25°C using a B-type rotational viscometer with a rotor rotation of 6 rpm, and η 2 is a viscosity as determined at 25°C using a B-type rotational viscometer with a rotor rotation of 12 rpm. Component (B): a thermally conductive inorganic filler having a Mohs hardness of ≥6 and an average particle size of 5-20 μm. Component (C): a thermally conductive inorganic filler having a Mohs hardness of ≤5 and an average particle size of 0.5-5 μm. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a reactor such that an iron powder-dispersed type epoxy casting material with which magnetic powder is mixed by ≥80 mass% has both flexibility and heat resistance, by using core shell type powder having a stable particle shape, usable even at high temperature, and existing in a system stably for a long period, especially, resin powder which stably toughens in a large-amount mixing system of special metal powder, i.e., magnetic powder. SOLUTION: The reactor is made of a curable resin composition including an epoxy resin, a curing agent, iron powder, and core shell type resin powder. he curable resin composition being acrylic resin includes: the iron core by 80 to 92 mass% of the whole composition; and the core shell type resin powder by 3 to 60 mass% of the epoxy resin, and a shell of the core shell type resin powder is cross-linked.
