FB-30 Nano Precipitated Barium Sulfate is a high-performance functional filler developed by Yunfu Hongzhi New Materials Co., Ltd. using an exclusive sulfuric acid process with stringent parameter control and multi-stage分级 filtration to ensure uniform crystallite size distribution. Surface-modified with silica-alumina, it delivers exceptional dispersion stability, ultra-low surface energy, and outstanding compatibility with organic resins. Its ultrafine median particle size (D50 = 0.03 µm), high purity (≥97.0 wt% BaSO₄), and superior whiteness (≥96.0%) make it ideal for demanding B2B applications where optical clarity, color fidelity, and rheological control are critical. It is widely adopted in premium industrial coatings, automotive OEM and refinish paints, water-based decorative systems, pigment dispersions, and high-gloss ink formulations across global manufacturing supply chains.
1. Ultrafine D50 of 0.03 µm ensures exceptional gloss, transparency, and color strength in pigment systems.
2. Silica-alumina surface treatment enhances suspension stability, thixotropy, and long-term dispersion integrity.
3. High purity (≥97.0 wt% BaSO₄) and absence of sulfides eliminate odor, black specks, and batch-to-batch instability.
4. Low oil absorption (24 g/100g) improves formulation efficiency and reduces resin demand without sacrificing film integrity.
Store in a cool, dry, well-ventilated area away from direct sunlight and moisture. Shelf life is 24 months from date of manufacture when stored unopened under recommended conditions. Transport as non-hazardous general cargo; avoid contamination and physical damage during handling. For optimal dispersion, add FB-30 during the grinding/milling stage at 5–25% loading relative to total solids. Use appropriate PPE (dust mask, gloves, safety goggles) when handling to minimize inhalation or skin contact with fine powder.; Storage condition: 25 kg bag; Shelf life: 25 kg bag; Pack size: 25 kg bag
