Matting and Flatting Agents and Anti-Corrosion Pigments for Coatings, Paints and Inks
For manufacturers of coatings, paints and inks, the difficulties associated with meeting stricter environmental standards, adapting to new application or print technologies, and fulfilling the rigorous performance demands of end-users never stop.
For the past 50 years, we have helped customers meet those challenges by offering a diverse line of precipitated silica products for use in a variety of liquid, powder and gel-based coatings, paints, lacquers and varnishes:
- PPG LO-VEL® silica flatting and matting agents reduce the gloss of a variety of products including coatings, paints, lacquers, varnishes and inks, while providing lower viscosity and better stir-in capability. A broad array of non-treated and wax-treated products, covering a wide range of particle sizes, grind values and surface areas have been designed to lower manufacturing costs through improved incorporation times, dispersion stability and anti-settling behavior in solvent-borne and water-borne coatings.
