Evonik's ACEMATT® range adds three new matting powders

● High extinction efficiency, high transparency

● Very fine surface touch

● Universal product, especially suitable for clear coat

Evonik is expanding its ACEMATT® range and has launched three high-efficiency general-purpose matting powders based on precipitated silica: fine-grained ACEMATT® OK 390, ACEMATT® HK 390, and general-purpose silica matting powder ACEMATT ® HK 520
.
The three new silica matting powders combine high efficiency, deep matting, high transparency and a very fine surface feel for water- and solvent-borne systems, as well as paint and clear coat formulations
.

Delicate touch and high transparency

"The three new matting powders have excellent clarity and provide a deep matt surface without white fog, especially for clear coatings
," said Maximilian Morin, head of Evonik's Industrial and Transportation Coatings Market
.
The main application areas of these three products include plastic coatings such as notebook computers and smartphones, and wood coatings such as parquet floors, table tops, and kitchen countertops
.

In wood applications, the related products impart high transparency to coatings, making texture effects clearly visible, while in automotive interior applications such as dashboards and trims, silica matting powders also provide a glare-free matte finish
.
In addition, matte formulations are also gaining popularity in exterior paint applications
.

ACEMATT®OK 390 is surface-treated, ACEMATT®HK is not, both products are silica matting powders with extremely small particle size
.
Despite the smaller particle size, during use, almost the same amount of new matting powder can be used to obtain the same depth of matting effect as the larger particle size product
.
Thomas Klotzbach, head of application technology at ACEMATT®, said: "This allows them to produce very fine surface textures while maintaining the same extinction efficiency without sacrificing transparency
.

Expanding ACEMATT® Product Portfolio

“Three new products complete the Evonik ACEMATT® portfolio
,” said Maximilian Morin.
“Currently, the range covers both surface-treated and untreated silica matting powders, including fine particle matting powders, long-lasting matting powders The market-proven ACEMATT® OK 520 is the same high-performing, unwaxed ACEMATT® HK 520.

”

Untreated silica matting powders such as ACEMATT® HK 390, ACEMATT® HK 520 have a major advantage compared to silica matting powders with wax surface treatment: better distribution in aqueous systems, resulting in Prevents uneven particle distribution in some plastic coatings and creates a smooth deep matt surface
.
In addition, post-treated precipitated silica matting powders such as the new ACEMATT® OK 390 do not settle during storage and are more stable in coatings
.

good dispersion

In addition to providing a refined appearance and delicate touch, these three new silica matting powders have minimal viscosity impact on coating formulations and excellent dispersion properties, making them ideal for a wide variety of coating applications
.

Currently, the paint and coatings industry is changing
.
The industry's demand for high extinction efficiency and high-quality waterborne coating systems is increasing, and customers are demanding a fine-tactile surface coating
.
With this in mind, Evonik has launched three new ACEMATT® products to meet these needs
