摘要

A filler material that includes a metal fluoride compound which is coated with silica. The filler material can be used in various types of covering agents. The filler material can be used partially or fully as a pigment extender in a covering agent such as paint to improve the properties of the paint. The filler material in the pigment extender can improve the hiding power of many types of paint formulations. The filler material in the pigment extender can be useful in flat paints that require relatively low sheen values. A pigment extender can include microcrystalline.silica, nepheline syenite and/or a silica coated metal fluoride.
