Use: Fluoroboric acid is the main component of electroplate liquid. It can be used as catalyst for alkylation and polymerization, and is the material to make various fluoborate. Its 2.5% solution can be used to electrolytically polish pure aluminum. Moreover, it can be used to clean and corrode metal surface oxide and silicate film.
Packing: Pack in 6kg, 25kg, 30kg or 250kg polyvinyl plastic drum.Basic Info-

Air and Water Reactions:Soluble in water with release of heat.
Reactive Group:Acids, Strong Non-oxidizing
Reactivity Alerts:Known Catalytic Activity
Reactivity Profile:FLUOROBORIC ACID is a strong acid. Reacts exothermically with chemical bases (examples: amines, amides, and inorganic hydroxides). These reactions can generate dangerously large amounts of heat in small spaces. Dissolution in water or the dilution of a concentrated aqueous solution may generate significant heat. Reacts with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Can initiate the polymerization of certain alkenes. Reacts with cyanide compounds to release gaseous hydrogen cyanide. Generates flammable and/or toxic gases in contact with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates. May catalyze (increase the rate of) chemical reactions. Attempted drying of the acid with acetic anhydride caused an explosion at 0°C [J. Organomet. Chem., 1975, 94, 319].
