It is especially suitable for use as a filler for resins. When contained in a curable resin composition, the filler imparts not only excellent dry-state heat resistance but excellent thixotropic properties, excellent slump resistance, and satisfactory storage stability. When used in a plastic, the filler has excellent dispersibility and imparts excellent insulating properties, etc. When used in a coating material or ink, the filler imparts excellent water resistance, etc.</p> |
