ACEMATT® 3400 is the new matting agent in the ACEMATT® product family from Evonik Resource Efficiency GmbH, specially developed for high-transparency clear coatings and soft-touch coatings with smooth surfaces.

ACEMATT® 3400 is a surface-treated, thermal silica with mediumparticle size of 7.5 µm. The improved grind performance results in a smooth surface finish with outstanding optical and haptic properties. 

This highly efficient silica is intended for use in clear coatings and water- and solvent-based coatings. Typical application fields include wood coatings, plastics, and automotive coatings. In addition, this new type of matting agent can be used in highsolids and low-VOC formulations.

In regards to rheology, the special after-treatment of ACEMATT® 3300 and ACEMATT® 3400 prevents the adsorption of associative thickeners in water-based systems. Likewise, when formulated with particular polyurethane binders, it can also improve the softtouch feel.

ACEMATT® 3400 can be easily incorporated into the formulation; no high shear forces are needed, thus, the bead mill can be skipped. Furthermore, ACEMATT® 3400 can be added to the coating formulation at the end of the process, allowing for a postadjustment of the gloss level.

ACEMATT® matting agents are high-performance silica developed for gloss reduction in a vast range of applications in the paints and coatings industry. 

Our best-in-class recommendations for high-quality coatings with excellent transparency are the family of thermal silica ACEMATT® TS 100, ACEMATT® 3300, and ACEMATT® 3400.
