Silica Powder for Coatings, Plastics & Industrial Applications
High purity silica powder with customizable particle size for coatings, plastics, rubber and industrial formulations.
KOSNANO is a professional silica powder manufacturer headquartered in China. We are committed to providing high-purity, customized nano-silica to customers in over 30 countries. Our silica powder is derived from natural high-purity quartz sand. Our team has over 20 years of experience in the production and operation of silica processed by gas-phase method, precipitation method or sol-gel method. The product quality is outstanding, with a SiO₂ content of ≥99.8% and the content of impurity ions (Na⁺, Fe³⁺, Cl⁻) strictly controlled at the ppm level.
The particle size range of Cosnano silica powder is from 20 nm to 500 nm, and the specific surface area is 150-750 m²/g. It can also be customized according to your requirements. KOSNANO serves customers in a wide range of application fields, including coatings, plastics, rubber, adhesives, inks, cosmetics and textiles. All of our silica products exhibit excellent reinforcing, matting, anti-settling and thixotropic properties.

Why Choose KOSNANO's Silica Powder
1. Ultra-high purity: SiO₂ ≥99.8%, impurity (Na⁺, Fe³⁺, Cl⁻) content controlled at the ppm level. KOSNANO’s silica can meet the most stringent formula requirements for electronic and food contact coatings.
2. Precise particle size control: The D50 particle size range is from 20 nm to 500 nm, with a narrow particle size distribution (D90/D10 ≤3.0). Our products can ensure the consistency of quality between batches as verified by laser diffraction (LS 13 320 analyzer).
3. Flexible surface treatment: We can provide you with hydrophilic or hydrophobic surface modification (silane, siloxane or fatty acid treatment). Ensure that your product has excellent dispersibility in water-based, solvent-based and UV-curable systems.
4. Full-process traceability: The factory’s ISO-certified production line undergoes ICP-MS, BET and laser particle size analysis for each batch. For each shipment, we provide documents such as COA (Certificate of Analysis), MSDS, and TDS.
5. Global Supply Chain: Quick delivery, factory direct sales, minimum order quantity 25 kilograms, DDP/FOB/CIF terms available. The samples will be sent out within 2 to 3 working days.
