Form supplied and packaging
Supplied in 200 liter sheet steel drums with HDPE inner lining and in 60 liter metal drums with HDPE inner lining. Supply in small containers, tanks or in tank trucks is also possible.
Properties
When stored for relatively long periods it may turn dark in color without losing its application-related properties. On dilution with water, hydrolysis ensues with liberation of methanol. A corrosive, highly acidic mixture of boric acid, hydroxyfluoroboric acids and tetrafluoroboric acid is produced. The vapors released into the air are corrosive. Due to its catalytic properties Boron trifluoride-Methanol adduct reacts with numerous organic compounds.
