Ammonium Bifluoride 98% Technical

Ammonium Bifluoride 98% Technical (CAS 1341-49-7, molecular formula NH4HF2) is a process chemical for electronics and metal finishing, where trace metal content and particle contamination matter as much as headline assay. China Chemicals supplies it at 98% min in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as ABF, Ammonium Hydrogen Difluoride, Ammonium Acid Fluoride. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Glass frosting, etching and decorative marking
Oxide removal in aluminium and stainless pretreatment
Scale and silica removal in oilfield acidising
Ceramic and silicon surface conditioning
Electroplating bath additive
