Our industrial hydrofluoric acid offers 75%, 80% and 85% concentration options, with strict batch control to ensure consistent acidity and corrosive performance, eliminating variability that could compromise precision processing results.
With targeted corrosive action on metals and silicon compounds, our 85% hydrofluoric acid delivers uniform, controllable results in precision etching and surface treatment, with strict impurity control to minimize unwanted side reactions in production.
Every batch undergoes strict testing for heavy metals, arsenic and other critical impurities, with full compliance documentation provided. Our production and packaging processes adhere to global chemical safety standards, ensuring safe handling and transport for industrial users.
We offer end-to-end support for bulk buyers, including free sample provision, custom concentration and packaging solutions, and 12-hour rapid inquiry response, with a professional technical team to address your application and safety questions.
Our hydrofluoric acid is a critical material across high-demand industrial sectors: it is the preferred solution for metal etching, precision surface treatment and cleaning of metal components in industrial parts manufacturing; it is widely used in glass frosting, engraving and precision processing for architectural glass, optical components and decorative glass products, thanks to its strong reactivity with silicon-containing materials; it supports wafer cleaning, silicon etching and surface treatment in semiconductor and electronic manufacturing; it is a key raw material for fluorine-containing compound and inorganic fluoride production in chemical synthesis; it also serves agricultural formulation production with our compliant agriculture grade options.
We provide flexible, corrosion-resistant packaging to match your production scale: IBC Drum (1200 KG per drum, 24 MT per 20'FCL), 35KG Drum (35 KG per drum, 25.2 MT per 20'FCL), 220KG Drum (220 KG per drum, 17.6 MT per 20'FCL), with custom packaging and labeling available on request.
Store hydrofluoric acid in a cool, dry place, away from direct strong light and heat sources. It must be kept in tightly sealed, corrosion-resistant plastic containers (as it corrodes glass and most metals), and isolated from incompatible substances to prevent hazardous reactions, with dedicated storage areas for chemical safety compliance.
We partner with professional chemical freight forwarders to ensure compliant, on-time global delivery, with full transparency via cargo photos before and after container loading, and customized shipping arrangements to meet your timeline and regional transport regulations.
