- Product Highlights
- Available in a range of particle distributions and packing configurations, HIFILL offers versatile filling options and cost effective performance in a broad range of liquid and powder coatings. With exceptional whiteness, HIFILL is ideally suited for use in brightly colored and contractor grade trade paints and masonry coatings. The low oil absorption of HIFILL can help maximize loading levels in either water or solvent based systems with only minimal impact upon viscosity.
- The appearance and functional properties of HIFILL provide reinforcement in filled PVC plastic and rubber applications and impart whiteness and opacity to adhesives, sealants, stuccos, and caulks. Formulators use high HIFILL loadings to reduce raw material costs while enhancing the mechanical, optical, and extrusion properties of their compounds.
- All HIFILL grades are processed with rigid adherence to statistical and quality assurance programs Covia QIPSM. The result is chemical purity and consistently uniform particle size distributions for predictable results and reliable service.
