<P>PROBLEM TO BE SOLVED: To provide a light-diffusive dimethylsilicone rubber composition which is excellent in weatherability, and provides a cured material having both the total light transmittance and the light diffusivity. <P>SOLUTION: The light-diffusive dimethylsilicone rubber composition is one in which 0.1 to 50 pts.mass of a light diffusing agent composed of fine glass beads of 150 μm in average particle diameter is added and dispersed in 100 pts.mass of a transparent or translucent uncrosslinked dimethylsilicone rubber blend composed of a dimethylpolysiloxane having two or more alkenyl groups bonded to silicon atoms of both molecular chain terminals and/or the midway of the molecular chain in one molecule or having both molecular chain terminals blocked with two or more hydroxyl groups or alkoxy groups in one molecule, or the dimethylpolysiloxane and an inorganic filler, or the dimethylpolysiloxane, an inorganic filler and a wetter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
