摘要:
A thermosetting resin composition capable of providing a molding, such as a resin sheet, that excels in not only dielectric characteristics but also dimensional stability at high temperature and even after exposure to high temperature thermal history, exhibits little dimensional change by the thermal history, namely, exhibiting low linear expansion coefficient. There are further provided a resin sheet and resin sheet for insulated substrate produced from the thermosetting resin composition. In particular, there is provided a thermosetting resin composition comprising an epoxy resin of 100 to 2000 epoxy equivalent, an epoxy resin hardening agent consisting of a phenolated compound, and a layered silicate, and are further provided a resin sheet comprised of the thermosetting resin composition and a resin sheet for insulated substrate comprised of the resin sheet.
摘要:
A preliminary-cured material permits reduced surface roughness of a roughening-treated surface, and increase of an adhesive strength between a cured object and a metal layer. The preliminary-cured material is obtained by advancing curing of an epoxy resin material that contains an epoxy resin, a curing agent, and a silica. The preliminary-cured material includes a first principal surface to be roughening-treated, and a second principal surface. The silica includes a first small particle-diameter silica whose particle diameter is not smaller than 0.01 μm but smaller than 0.5 μm, and a second large particle-diameter silica whose particle diameter is not smaller than 0.5 μm but not larger than 20 μm. The first small particle-diameter silica is localized to exist in large quantity on a side of the first principal surface, and the second large particle-diameter silica is localized to exist in large quantity on a side of the second principal surface.

Mean particle diameter of the silica particles is equal to or less than 1 μm. An amount B (g) of the silane coupling agent used for surface treatment, per 1 g of the silica particles in the silica component, is within a range between 10% to 80% with regard to a value C (g) per 1 g of the silica particles, which is calculated by the following formula (X). C (g)/1 g of Silica Particles=[Specific Surface Area of Silica Particles (m2/g)/Minimum Area Coated by Silane Coupling Agent (m2/g)] Formula (X)
