≥99% Potassium Bifluoride (KHF₂) CAS 7789-29-9 for Glass Etching, Fluoride Preparation, and Fine Chemical Applications

1. Product Overview

Potassium Bifluoride (KHF₂) is an important inorganic fluoride material and a key fluorine source product in the fluorochemical industry chain.

≥99% high-purity potassium bifluoride features stable chemical properties and high fluorination reactivity. It is mainly used in glass etching, metal surface treatment, fluoride preparation, welding fluxes, and fine chemical applications.

Compared with ordinary industrial grade products, high-purity potassium bifluoride places greater emphasis on main content, impurity control, moisture content, and batch-to-batch stability.

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

7. Frequently Asked Questions (FAQ)

Q: Which industries primarily use potassium bifluoride?

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

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

A: Potassium bifluoride contains the HF₂ structure and has stronger fluorination reactivity, commonly used in etching and special fluorination processes; potassium fluoride is mainly used as a general potassium-based fluoride raw material.

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

A: Both are acid fluorides, but with different cations. Potassium bifluoride is suitable for potassium-based applications, while ammonium bifluoride is more commonly used in glass etching and the fluorochemical industry.

Q: Why is high purity required for potassium bifluoride?

A: High purity minimizes the impact of impurities on etching effects, reaction stability, and final product quality.

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

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