POWDER MATERIAL CONTAINING NEEDLE SINGLE CRYSTAL INORGANIC POWDER, COATING MATERIAL, LIQUID POWDER DISPERSION AND METHOD FOR USING THEM

摘要

A resin-coated powder material, characterized in that it comprises a needle single crystal inorganic powder and, coated on the surface thereof, at least one organic resin selected from a silicon-containing resin and a fluorine-containing resin; a coating material, characterized in that it comprises a silicon-containing resin and/or a fluorine-containing resin and a needle single crystal inorganic powder of zinc oxide; and a method for modifying the surface of a base material, characterized in that it comprises applying a liquid inorganic powder dispersion comprising a needle single crystal inorganic powder and a resin onto a plastic base material or an inorganic base material, to thereby impart water repellency to the surface of the base material.
