Overview
HMMAT 708 is a high-performance silica matting agent with a special surface treatment, D50 7.5–8.0 μm, and low oil absorption of 150–200 g/100g. Its lower porosity and special treatment make it suited to UV-cure systems where conventional organically treated grades may affect cure performance. Primary applications are UV wood coatings and UV inks.
