Hydrofluoric Acid 60% Hydrofluoric (HF) acid is used mainly for industrial purposes (e.g. glass etching, metal cleaning, electronics manufacturing). HF acid also may be found in home rust removers.HF solutions are particularly used in the glass industry (frosting, satining), in crystal activities (defrosting)and in ceramics activities.Also, in metallurgical field, these grades are used in surface treatment, cast-iron-steel and stainless steels cleaning.HF solutions are also used in other more general applications such as the separation of rare earth, or utilized as a catalyst. Hydrofluoric acid attacks glass, concrete, and many metals. It also attacks carbonaceous natural material such as woody materials, leather, and rubber.
General Specifications : Appearance, liquidColour, colourlessOdour, pungent. Some materials resist the corrosive action of the acid, such as platinum, wax, polypropylene, polyethylene, and Teflon. In contact with metals with which it will react, hydrogen gas is liberated and the danger exists of a spark or flame resulting in an explosion. HF is used in many labs and in the glass shop on a regular basis. It should always be stored in plastic bottles. Containers of HF should be stored in secondary containers made of polyethylene in areas separate from incompatible materials. All work with hydrofluoric acid should be conducted in a fume hood to prevent exposure by inhalation. Splash goggles and Neoprene gloves as well as laboratory coats should be worn at all times to prevent eye and skin contact.
