Independent verification of Potassium Silicofluoride on third-party scientific databases:
Yes. Phosphor / optical-grade K₂SiF₆ is supplied at 99% min purity with low Fe, Cu, and Cr impurities to minimise quenching. Particle size is controlled to D50 ≈ 15 µm for direct LED-package use, and powders can be supplied unwashed or pre-washed with HF for activation.
Potassium Silicofluoride is supplied in HDPE woven bags with inner LDPE liner (25 kg / 50 kg net), HDPE drums (25 / 50 / 250 kg), and FIBC jumbo bags (500 / 1000 kg) for solid grades. Liquid grades ship in HDPE-lined steel drums (250 kg) or 1000 L IBC totes. Custom packaging — including nitrogen-blanketed, moisture-tight, or food-grade containers — is available on request.
Standard MOQ is 1 metric tonne for solid grades and 200 kg for liquid grades; pilot quantities of 5–25 kg are available for R&D qualification. Stock items dispatch within 7–10 working days from confirmed PO. Made-to-order grades and large export consignments require 3–4 weeks. Indian deliveries by road typically reach 4–7 days; export FCL shipments depend on destination port.
Yes. A 16-section GHS-format SDS is dispatched with every shipment and is also available in advance from marketing@sbfluorochem.com. A batch-specific COA accompanies every consignment and is emailed before dispatch for goods-receipt verification. Test methods follow IS / ASTM / USP / IP / EP as applicable.
