Our 70% HF solution is an aqueous grade that is a clear, colorless, corrosive fuming liquid with a sharp, pungent odor. It is 100% soluble in water and is not flammable. As with all grades of HF, 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.Information provided by Honeywell |
