ABSTRACT:
Silicone resin-based molding compositions filled with spherical glass bodies, i.e., void-free glass beads or hollow glass spheres, have the possibility to give molded articles colored in white or light-tone colors different from conventional molding compositions filled with other inorganic fillers which are rather highly abrasive against metal surfaces of the apparatus employed for processing the molding compositions and which causes dark stains to the molding compositions leading to the necessity to color them in black or dark-tone colors in order to mask the stains. The molded articles fabricated with the molding compositions of the present invention colored in white or light-tone colors are very attractive where sanitary cleanliness or fashionableness is important.
