Product Description

Hydrofluoric Acid 49% 50% 55% 70% (HF) for Glass Treatment

1. Product Description

Hydrofluoric Acid is an aqueous solution of hydrogen fluoride gas, a clear , colorless, smoky corrosive liquid with a sharp pungent odor. hydrofluoric acid is a weak acid that is exremely corrosive and strongly corrodes metals, glass and silicon-containing objects, Inhalation of steam or contact with skin can cause burns that are difficult to cure.

The laboratory generally used fluorite and concentrated sulfuric acid to make it, which needs o be sealed in plastic bottles and kept in a cool place
