Expanding the ACEMATT® product line, Evonik has released three matting agents based on precipitated silica: the fine-particle products ACEMATT OK 390 and ACEMATT HK 390, and the versatile silica ACEMATT HK 520. They are characterized by a combination of efficient, ultra-deep matting, high transparency, and extremely fine surface haptics. All three can be used in water- and solvent-based systems as well as in pigmented and clear formulations. Applications include coatings for plastics, wood coatings, and interior and exterior automotive coatings. They show little influence on the viscosity of the formulation and have excellent dispersion behavior.
