Product description:Colourless liquid. Melting point - 90 ℃. The boiling point of 130 ℃. Miscibility with water or alcohol. A strong acid. Partially hydrolyzed in water, forming boron hydrogen fluorine ion (BF3OH -). With metal salt crystals was formed. 20% aqueous solution refractive index (n20D) 1.3284. Have a tear. Have strong corrosion resistance. Goods are often 48% aqueous solution or 54% ether solution, inflammable ether solution.Used in cleaning and metal surface oxide and silicate film etchant, aluminum and alloy plating before cleaning. 2.5% solution for pure aluminum electrolytic polishing and removed from the metal substrate to lotion of coating and plating parts. Used as alkylation and polymerization catalyst, preservatives, chemical reagents, as well as the preparation of raw materials of various kinds of fluoboric acid salt. Used for acetaldehyde synthesis catalysts, metal surface cleaning agent, lead electrolytic polishing agent, the diazonium salt stabilizers, etc.; Used as the stabilizer of diazonium salts, also used in the electrolysis industry, etc.; Used in metal and alloy electroplating in front of the clean surface. Aluminum and steel phosphate passivation preservative composition, lead battery optimum soluble lead electrolyte, enhance the capacity of crude oil in oil field exploitation, manufacture diazonium salt stabilizers and the raw materials of various fluoboric acid salt, alkylation and polymerization catalyst. The metal surface oxide and silicate membrane cleaning and etch.
