Aqueous Hydrofluoric Acid (HF) – 20% to 75%
Hydrofluoric acid is a dilution of hydrogen fluoride (HF) in water and is a precursor to almost all fluorine compounds. It is a colourless solution that is highly corrosive, capable of dissolving many materials.
DERIVADOS DEL FLUOR, a global leader in the manufacture of aqueous hydrofluoric acid, offers a wide range of high-level HF grades to meet market and customers´ demands.
Our principles for aqueous HF supply focus on safety, service and quality:
• We deliver aqueous HF in various packaging solutions, such as IBCs, drums and jerrycans, in accordance with the main quality and homologation standards and always focused on improvement and customers´ needs.
• We also supply aqueous HF in our own ISO containers, built to the highest safety standards and handled in-house.
• Close cooperation with our customers enables us to offer tailored products in terms of grades and quality, with special formulations and the blending of solutions on request. We are also currently developing special formulations for a higher performance in pickling for the stainless-steel process.
• We assure sufficient storage capacity to provide a reliable service and customized logistical solutions. We offer a quick service in Europe, with just-in-time delivery to our customers´ facilities.
• Safety is a core value for DDF, and our track record is representative of this commitment. We provide a dedicated technical advisory service to our clients to guarantee a safe handling and transport of the product.

Aqueous Hydrofluoric Acid (HF)
Aqueous Hydrofluoric Acid is a versatile reagent used across industries that require controlled concentrations and reliable performance. It is widely applied in glass etching, metal surface treatment, mineral flotation, and semiconductor processing, where precision and consistency are critical.
Industry trend: Recent developments highlight Aqueous HF’s role in energy storage systems, particularly in lithium-ion battery chemistry, supporting the boom in EVs and renewable integration.
APPLICATIONS
Aqueous hydrofluoric acid (HF), one of the strongest inorganic acids, is commonly used in the manufacture of organic and inorganic fluoride compounds.
It is widely used in the pickling of stainless steel, in the semiconductor industry as an etchant and cleaning agent, in the manufacture of ceramics, in the purification of graphite, ferrosilicon and quartz, in the electropolishing and pickling of metals (surface treatments), in the etching and frosting of glass, in the chemical industries, and in cleaning chemical solutions.
