Why SEMISIL H100 Fits Waterborne Coatings
Untreated high-purity fumed silica disperses cleanly in aqueous systems without introducing conductivity issues that plague some treated grades.
Competitive context: Common alternatives: ACEMATT TS 100, ACEMATT OK 412. SEMISIL H100 matches the relevant performance window with the same particle size range as the legacy grades, enabling clean reformulation paths.

FAQ — Waterborne Coatings
+What treat rate of SEMISIL H100 is recommended for waterborne coatings?
Typical dosage is 1.5 – 4.0 wt% on total formulation (DFT-dependent). Fine-tune ±0.5 wt% based on your DFT and target gloss (60° gloss down to 5 GU achievable at 2.5 – 3.5%).
+How does SEMISIL H100 compare to ACEMATT TS 100, ACEMATT OK 412 for this application?
Common alternatives: ACEMATT TS 100, ACEMATT OK 412. SEMISIL H100 matches their performance window at 30 – 45% lower landed cost from Chinese manufacture, with the same particle size range so existing formulations port cleanly.
