Overview
HMMAT 207 is a high-performance silica matting agent with an organic surface treatment and D50 7.0–7.5 μm. It delivers gloss reduction through microscopic surface irregularities, with excellent dispersibility, high chemical stability and inertness, and strong matting efficiency. Suited for wood coatings, industrial coatings, and automotive refinish.
