Applications

Hydrofluoric Acid 49% Solution is a colorless liquid. Hydrofluoric Acid, 49% Solution, contains 49% Hydrofluoric Acid mixed with a balanced quantity of Water. It can be used for the electronic industry to perform cleaning of silicon wafers and etching of semiconductors, as these delicate applications require ultra-purified solvents. Hydrofluoric acid is used in a variety of over-the-counter products such as toilet bowl cleaners, concrete cleaners, and metal polishes. However, the uses for industrial applications are far more numerous. hydrofluoric acid is used for quartz purification, glass etching, refrigerant manufacturing, pharmaceuticals, high octane gasoline, aluminum production, plastics, electrical components, and fluorescent light bulbs.
