Issue 8/2019 - New matting agents improve the optical performance and haptic feel of coatings

New matting agent enhances optical properties and haptic
coatings Evonik has recently introduced a new matting agent ACEMATT^®3400
with high transparency and soft touch.

ACEMATT^®3400 is a surface-treated, medium-sized fumed silica matting agent with an average particle size of 7.
5 μm, a new matting agent in the ACEMAT^® product range of Evonik, specially developed
for varnishes with high transparency requirements and coatings with smooth surfaces and soft touches.
This matting efficiency matting agent is ideal for a wide range of clear, waterborne and solventborne coatings, typical applications include wood, plastic and automotive coatings
.
In addition, it can be used in high solids and low VOC formulations
.

The product has a low fineness, which makes the coating surface very smooth, while having excellent optical properties and haptics; Its special post-treatment prevents the adsorption of association thickeners in waterborne coating systems; It can be added to the formulation later in the paint production process, and the gloss can be adjusted later; It can be easily incorporated into recipes without the need for high shear forces and without the use of a bead mill
