Hydrofluoric acid for clean metal surface
Specification: Classification: Hydrofluoric Acid ; CAS No.: 7664-39-3 ; Purity: 100%,70%,50% ;
Industrial hydrofluoric acid
Hydrofluoric acid is aqueous solution of hydrogen fluoride. It's colourless and transparent, having strong and irritative smell and causticity. It can pickling such materials containing SiO 2 as glass quickly.
CLEAN METAL SURFACE
Specifications:
[Usage] mainly used in the production of salts fluoride to engrave and erode the glass, clean metal, treat surface, and so on
[Packing]with polyethylene plastic drum (10kg/25kg/200kg each drum); iron drum with the plastics inside (200kg each drum).
[Note] the content of HF of the products is 35-70%. The production will be organized according to the requirements of the clients.
