Why SEMISIL H100 Fits PU (Polyurethane) Coatings
Chemical stability against polyols and isocyanates — no premature reaction in 2K PU systems, no skinning in 1K PU systems.
Competitive context: Direct alternative to ACEMATT TS 100 in 2K PU clearcoats. SEMISIL H100 matches the relevant performance window with the same particle size range as the legacy grades, enabling clean reformulation paths.

FAQ — PU (Polyurethane) Coatings
+What treat rate of SEMISIL H100 is recommended for pu (polyurethane) coatings?
Typical dosage is 2.0 – 5.0 wt%. Fine-tune ±0.5 wt% based on your DFT and target gloss (20°/60° matt range across 5 – 30 GU).
+How does SEMISIL H100 compare to ACEMATT TS 100 in 2K PU clearcoats for this application?
Direct alternative to ACEMATT TS 100 in 2K PU clearcoats. 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.
+Can I request samples for pu (polyurethane) coatings trials?
