CAS No.: 768-49-4
Properties: It is a white crystal with relative density of 2.08. It is soluble in water, but insoluble in ethanol. Its aqueous solution can etch glass. When heated sodium hydrogen fluoride decomposes into sodium fluoride and hydrogen fluoride.
|NaF content||98% min|
|Water insoluble matter||0.7% max|
|Moisture (H2O)||0.5% max|
|Mesh Size:Through 325 mesh||80% min|
Application: It is used in welding flux, toothpaste additive, preservative, bactericide, slagging medium of metallurgy, adhesive, paper-making and construction industry.As a phosphating accelerator in the coating industry, the phosphating solution is stabilized, the phosphating is refined, and the performance of the phosphating film is improved. Aluminium and its alloys are phosphatized to block Al3+, which has a highly harmful negative catalytic effect, so that phosphating can smoothly carry out wood preservatives, agricultural pesticides, brewing industry fungicides, pharmaceutical preservatives, welding fluxes, and alkaline zinc. Acid galvanizing additives and enamel, paper industry, etc.
