Hydrofluoric Acid
Hydrofluoric acid (17870)
Aqueous 70% Solution
Overview
Our 70% HF solution is an aqueous grade that is a clear, colorless, corrosive fuming liquid with a sharp, stinging odor. It is 100% soluble in water and is not flammable.
70% HF is highly hazardous and needs to be handled and used with rigorous safety precautions. It can cause severe burns to all parts of the body in liquid and vapor forms. Specialized medical treatment is required for any exposure to 70% HF.
