Applications

It is used in coatings, inks, sealants, and adhesives for rheology control, and as a reinforcing agent in silicone rubber. In pharmaceuticals and cosmetics, it functions as a glidant and carrier for active ingredients.

Safety & Risks

Inhalation of airborne dust can cause respiratory irritation. Implement local exhaust ventilation and wear suitable respiratory protection. Avoid prolonged exposure to moisture, which reduces product performance.

Packaging

Available in 10–20 kg multi-wall paper bags or FIBCs lined with PE; stored in dry, closed areas to prevent contamination.
