Surface-treated fumed silica engineered for matting in coatings — a direct alternative to Evonik ACEMATT TS 100, with high oil absorption (300–380 g/100 g) for efficient gloss reduction.

SEMISIL H100 shares the same fumed-process base as standard fumed silica, but its surface is treated specifically for matting performance in coatings rather than thixotropic rheology. The result is efficient, haze-free gloss reduction at low loadings — a cost-effective drop-in alternative to Evonik ACEMATT TS 100.
Oil absorption of 300–380 g/100 g delivers strong matting efficiency, so target gloss is reached at lower addition rates.
A d50 of 8.0–11.0 µm produces a smooth, even matte surface without the gritty texture of coarser fillers.
BET 230–270 m²/g gives the structure needed for consistent micro-roughness across solventborne and UV systems.
SiO₂ ≥ 99%, pH 6–9 — compatible with a wide range of resin systems and low in ionic contaminants.

Standard SEMISIL fumed silica grades (150–380 m²/g) target thixotropic rheology in sealants, adhesives, and silicone systems. H100 is the matting specialist: same fumed-process base, but surface-treated to scatter light and cut gloss in coatings. If your application is sealant or adhesive rheology, choose a hydrophilic SEMISIL grade; if it is matting in wood, UV, or solventborne coatings, H100 is the right pick.
SEMISIL H100 is a surface-treated fumed silica matting agent for coatings — wood coatings, UV-curable topcoats, and solventborne systems where a smooth, durable matte finish is required without sacrificing transparency.
SEMISIL H100 is positioned as a direct alternative to Evonik ACEMATT TS 100, matching its high-oil-absorption, fumed-silica matting profile.
Loading depends on target gloss and binder, but the high oil absorption (300–380 g/100 g) means effective matting is typically reached at lower addition rates than coarser precipitated-silica matting agents. Start low and adjust to your gloss target.
