Each TDS lists SiO₂ content, particle size distribution (D50, D90), tamped density, oil absorption, moisture, pH, and gloss-reduction curves at 60° and 85° geometry. Loading recommendations and dispersion guidelines are included for major binder families.

Precipitated grades (GMATT series) offer the widest gloss range at lower cost and suit most solventborne and waterborne systems. Fumed silica (SEMISIL H100) is preferred when maximum transparency and very low haze are critical, such as UV-cure wood or high-clarity clears.

Yes. Select GMATT grades meet FDA 21 CFR 172.480 and EU 231/2012 for silicon dioxide in food-contact coatings. Request the specific compliance package from our certifications page to confirm the grade suits your end-use.

High-speed dissolvers (tip speed 12–18 m/s) handle most precipitated grades. Bead mills with 0.8–1.2 mm media are recommended for fumed silica or when D50 control below 5 µm is required. Over-grinding increases haze, so monitor particle size during milling.

Every production lot ships with a COA listing particle size (D50, D90), moisture content (<3%), ignition residue, and pH. Digital copies are available within 24 hours of shipment. COAs tie to full batch traceability records under our ISO 9001 system.

TDS documents are reviewed and updated quarterly. Revisions reflect any process changes, new test data, or expanded application guidelines. The revision date is printed on every sheet — always confirm you are referencing the latest version from our library.

Start with the TDS library to shortlist grades by particle size and target gloss, then validate your choice against a matching case study before requesting samples.
