Why SEMISIL H100 Fits Powder Coatings
Pure SiO₂ ≥ 99% prevents migration during melt flow and minimizes powder flow agent interference.
Competitive context: ACEMATT 3300 / 3600 typically — H100 cost-competitive. SEMISIL H100 matches the relevant performance window with the same particle size range as the legacy grades, enabling clean reformulation paths.

FAQ — Powder Coatings
+What treat rate of SEMISIL H100 is recommended for powder coatings?
Typical dosage is 0.5 – 2.0 wt% (post-blended). Fine-tune ±0.5 wt% based on your DFT and target gloss (60° 15 – 50 GU; texture / structured finishes).
+How does SEMISIL H100 compare to ACEMATT 3300 / 3600 typically — H100 cost-competitive for this application?
ACEMATT 3300 / 3600 typically — H100 cost-competitive. 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.
