Description

What is Ammonium Bifluoride?

Ammonium bifluoride is an effective fluoride source used for etching, surface treatment, and chemical processing applications where controlled fluoride activity is required. Supplied as white flakes composed of ammonium hydrogen fluoride (NH4HF2) with a minimum assay of 96.0%, it delivers consistent chemical composition for laboratory and industrial use.

The solid flake form supports measured handling compared to liquid fluorinating agents, enabling more controlled dosing when proper safety procedures are followed. This product is classified as acutely toxic and corrosive under GHS standards—appropriate engineering controls and personal protective equipment are required during handling.
