(57) [Summary] [Structure] The average particle size is 300 in the case containing the parts. After filling the filler (A) of μm or more, a polyol, The composition contains a polyisocyanate and a filler (B) and has a viscosity of 4 Pa.s. s or less, the hardness (Shore A) of the cured product is 50 or less, and the flame retardancy is UL94V-2 or more (test piece thickness 5 mm or less). A method for manufacturing an electric device, which is injected and cured at a vacuum degree of 0 Torr or less. [Effect] As well as conventional, excellent impregnation and adhesion can be obtained, and since the content of the filler can be increased, electrical equipment excellent in curability, crack resistance, flame retardancy and thermal conductivity. Can be obtained at low cost. |
