Hydrofluoric Acid Supplier — Industrial Grade HF

What Is Hydrofluoric Acid?

Hydrofluoric Acid (HF) is a solution of hydrogen fluoride in water. Unlike other strong acids, HF has uniquely dangerous properties — it penetrates skin readily and can cause systemic toxicity from fluoride ion absorption. For this reason, it is classified as a regulated substance and supplied exclusively to verified industrial end-users with appropriate safety infrastructure and handling procedures in place.

Glass Etching and Surface Treatment

Hydrofluoric Acid is the primary chemical used in glass etching, frosting, and polishing. It reacts with silicon dioxide in glass to form soluble fluorosilicate compounds. Applications include decorative glass frosting, optical glass cleaning, and precision etching of scientific glassware. It is also used in semiconductor manufacturing for silicon wafer cleaning and oxide removal.

Metal Pickling and Stainless Steel Processing

HF is used in mixed acid pickling baths (together with nitric acid) for stainless steel, titanium, and specialty alloys. The combination rapidly removes heat tint, scale, and surface contamination from weld zones and heat-affected areas, restoring corrosion resistance. It is an essential process chemical in stainless steel tube, sheet, and fitting production.
