Independent verification of Magnesium Fluorosilicate Hexahydrate on third-party scientific databases:
Yes — MgSiF₆·6H₂O is variously called magnesium fluorosilicate, magnesium hexafluorosilicate, or magnesium silicofluoride hexahydrate. All three names refer to the same compound. Our product is supplied as a free-flowing crystalline solid, soluble in water for industrial floor-hardener bath make-up.
Magnesium Fluorosilicate Hexahydrate 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.
SB Chemicals exports to over 35 countries across South-East Asia, the Middle East, Africa, Europe, and the Americas. We hold IEC, GST, and APEDA registrations.
