Product Overview
Ammonium Bifluoride Flakes, also known as ammonium hydrogendifluoride, is a highly versatile inorganic acid salt widely utilized across various heavy industrial sectors. It is prepared as a solid white crystalline flake, offering exceptional solubility in water and selected alcohols. Industrial facilities rely on this chemical for its acidic properties and its ability to supply active fluoride ions under controlled conditions. Alliance Chemical supplies this compound in precise packaging formats, ensuring secure containment and consistent physical properties for processing.
This compound acts as a powerful glass-etching agent, a critical reagent in electroplating, and an essential component in metal surface preparation. Due to its corrosive nature, handling ammonium bifluoride requires strict adherence to safe operational protocols. Alliance Chemical distributes a wide range of premium inorganic compounds directly to your facility, ensuring our high-purity flakes prevent the clotting and dust formation often associated with lower-grade alternatives. Our focus remains on delivering reliable industrial chemical solutions directly to your facility, backed by rigorous quality assurance and detailed documentation.
Why This Grade
Selecting the proper grade of ammonium bifluoride is critical to maintaining operational integrity in chemical processing and metal treating. Lower-grade alternatives with high trace-metal impurities can cause inconsistent etching rates and catalytic poisoning in sensitive plating baths. Utilizing our high-purity solid flake form ensures that the active concentration of fluoride remains within strict operational tolerances, preventing unexpected pH shifts during industrial workflows.
In applications such as oil well acidizing or industrial scale removal, selecting an incorrect grade can lead to the formation of insoluble calcium fluoride precipitates, which can permanently block geological formations or damage expensive piping. A reliable, dry flake form minimizes moisture absorption during storage, preventing caking and ensuring a consistent flow rate in dry feeders. Alliance Chemical provides this standard industrial grade to eliminate these failure modes and ensure predictable chemical performance in every batch.

Hazmat & Shipping
Ammonium Bifluoride Flakes is a regulated hazardous material classified under DOT regulations as UN1727, Hazard Class 8, Packing Group II. The proper shipping name is Ammonium hydrogendifluoride, solid. It is labeled with the signal word DANGER due to its severe toxicity and corrosive properties. Every shipment is dispatched in fully compliant, hazard-certified packaging designed to withstand transportation stresses. Alliance Chemical employs experienced logistics partners specialized in handling Class 8 materials, ensuring safe, compliant delivery to your facility.
Under the GHS framework, this material carries the hazard statements H301 (Toxic if swallowed) and H314 (Causes severe skin burns and eye damage). Personnel handling this material must utilize comprehensive personal protective equipment (PPE). According to safety guidelines, this includes a full-face respirator, chemical-resistant neoprene gloves, acid-resistant protective suits, and heavy-duty rubber boots. It is critical to review the safety guidelines before attempting to unpack or utilize this product.
Handling & Storage
Ammonium Bifluoride Flakes must be stored in a cool, dry, well-ventilated warehouse away from direct sunlight, maintaining temperatures ideally between 50°F and 85°F. This product is highly incompatible with glass, strong acids, strong bases, and moisture. Because it reacts with silicates, it will etch glass containers; therefore, it must always be stored in heavy-duty polyethylene, polypropylene, or fluorinated plastic drums. Ensure containers remain tightly sealed to prevent moisture absorption, which can cause caking and liberate toxic hydrogen fluoride gas.
Order & Documentation
Alliance Chemical provides comprehensive technical and regulatory documentation to simplify compliance and facility safety. A detailed Safety Data Sheet (SDS) is provided with every order to ensure your team is fully equipped with handling protocols. For specific lot verification, a Certificate of Analysis (COA) is available upon request. To secure your supply of Ammonium Bifluoride Flakes, you can Request a Quote for bulk volumes or Download the SDS directly from our online technical library.
