摘要

Finely grain filler, for white toning of first bonding agents, comprises composite materials or floor- and wall coating- materials, and silica sand grains as substrate, where the silica sand grains have a low ferric oxide content of 30-120 mg/kg, white colored pigment and at least one second bonding agent, the silica sand grains are sheathing from inorganic, the sheathed silica sand grains are loosely present, before their processing in the composite material. An independent claim is included for the preparation of the grain filler.
