Sodium Bifluoride
A white crystalline powder, readily soluble in water with an acidic reaction. Decomposes on heating or contact with acids to release hydrogen fluoride — a mild yet efficient solid fluorinating agent.
As a solid, sodium bifluoride is easier to store, transport and dose accurately than HF, acting as a stable fluorine source in metal treatment formulations, glass etching powders and cleaning agents. ANFA produces to customer requirements on assay, particle size and flowability (with or without anti-caking agent).
International trade names: Bifluoruro de sodio (Spanish), Bifluoreto de sódio (Portuguese), Бифторид натрия (Russian). Overseas buyers frequently search for this product under these local-language names.
