Introduction
ACEMATT OK 390: Fine-grained matting powder with wax surface treatment, excellent anti-settling performance in varnish and excellent feel. Made by precipitation production process, it has good matting efficiency and transparency.
Production process
Precipitation method: also known as wet process, that is, the silicate solution is neutralized with acid to precipitate amorphous silicon dioxide, and the material after filtration, washing and drying contains a small amount of water and some organic components. Silica with different surfaces and structures can be obtained by controlling different parameters during precipitation. Different drying methods can be used according to the required properties of the final product. The dried SiO2 will be ground and classified.
Advantages of precipitation process: strong matting ability, dry surface effect, good scratch resistance of paint film. Matt powder has good dispersion resistance, that is, as the dispersion time increases, the matting ability of matting powder will not change much.
