Applications

Hydrofluoric acid is used in the glass etching, electronic and chemical industries. Hydrogen fluoride is mainly used in the production of organofluorine compounds, aluminum and chlorofluorocarbons. Hydrogen fluoride is also used for separating uranium isotopes, as a catalyst in the petroleum industry, and in stainless steel pickling. Hydrofluoric acid is used as a pickling agent and used in the semiconductor materials.

Notes

Special handling precautions required. View MSDS prior to purchase. MSDS are available online at www.alfa.comIt is incompatible with metals, alkalis and moisture. May corrode metallic surfaces and glass. Store in a polyethylene container.
