Evonik's Coating Additives Business Line is expanding its Acematt product line with three efficient and universally applicable matting agents based on precipitated silica: the fine-particle products Acematt OK 390 and Acematt HK 390, and the versatile silica Acematt HK 520. The three new silicas from the specialty chemicals group are characterized by a combination of efficient, ultra-deep matting, high transparency, and an extremely fine surface feel. All three matting agents can be used universally in water- and solvent-based systems as well as in pigmented and clear formulations.
With the three new members of the Acematt family, Evonik is responding to changing requirements in the paint and coatings industry, where demand is growing for ever deeper degrees of matting and high-quality water-based coating systems, while customers are also looking for a fine surface feel fromi surface coatings.
