Overview
HMMAT 570 is a high-performance silica matting agent with a special surface treatment and D50 7.5–8.0 μm. It delivers gloss reduction through microscopic surface irregularities, with excellent dispersibility, high chemical stability, and strong matting effects. Suited for coil coatings, steel coatings, industrial coatings, and metal coatings.
