3、 Nature and Use

Extremely corrosive, with strong irritation and corrosive effects on respiratory mucosa and skin. Hydrogen fluoride and its aqueous solution are toxic and prone to deformities of bones and teeth. Non combustible, but able to react with most metals to generate hydrogen gas and cause explosions. Mainly used for etching glass and producing fluorine compounds.

4、 Packaging and Storage

The company adopts tank truck packaging, with a filling coefficient not exceeding 0.83Kg/L. Store in a cool and ventilated warehouse, away from sparks and heat sources. The temperature should not exceed 30 ℃ and should be stored separately from flammable (combustible) materials, alkalis, and edible chemicals. Avoid mixing storage.
