99% Ammonium Bifluoride (NH₄HF₂) CAS 1341-49-7 for Glass Etching, Fluoride Materials, and Fine Chemical Applications

1. Product Overview

Ammonium Bifluoride (NH₄HF₂) is an important inorganic fluoride product and a key derivative material in the hydrofluoric acid system.

99.32% ammonium bifluoride features high purity, good fluorination reactivity, and stable chemical properties. It is mainly used in glass etching, metal surface treatment, fluoride preparation, electronics industry, and fine chemical applications.

Compared with ordinary industrial grade ammonium bifluoride, the high-purity product places greater emphasis on main content, free acid, impurity elements, and batch-to-batch stability.

For the Russian market, this product is mainly targeted at glass processing enterprises, metal treatment companies, fluoride production enterprises, electronic material companies, and chemical raw material traders.

7. Frequently Asked Questions (FAQ)

Q: Which industries primarily use 99% ammonium bifluoride?

A: It is mainly used in glass etching, metal surface treatment, fluoride production, electronics industry, and fine chemical applications.   

Q: What is the difference between ammonium bifluoride and hydrofluoric acid?

A: Ammonium bifluoride is a solid fluoride product, making transportation and storage relatively more convenient; hydrofluoric acid is a liquid acidic fluoride system with different application methods.

Q: Why is purity control important for ammonium bifluoride?

A: High purity helps reduce the impact of impurities on etching effects, surface treatment quality, and chemical reaction stability.

Q: What is the difference between ammonium bifluoride and ammonium fluoride?

A: Ammonium bifluoride contains the HF₂ structure and has stronger fluorination reactivity, commonly used in etching and special fluorination processes; ammonium fluoride is mainly used for general fluoride applications.

Q: What documents are required for purchasing ammonium bifluoride in Russia?

A: Typically, COA, TDS, SDS, certificate of origin, and packaging information are required.
