Overview
HMMAT® 562 is a high-performance silica matting agent produced via a gel process with an organic surface treatment. Its D50 of 6.0–6.5 μm delivers gloss reduction through microscopic surface irregularities, with excellent dispersibility, high chemical stability, and strong matting effects. Suited for wood coatings and industrial coatings.
