Sodium fluoride is a colorless or white solid that is readily soluble in water. In general, choosing sodium fluoride instead of KF is based on economics. Apart from the fact that Sodium Fluoride is more readily available and still anhydrous, there is no mention of the synthetic advantage of sodium fluoride over KF.
Sodium fluoride is less efficient and the solubility of commonly used solvents is poor. If the disadvantages listed previously are not important, then Naf (sodium fluoride) is less hygroscopic and less expensive. In general, laboratory synthesis uses kf, and when enlarged into a plant program, Naf (sodium fluoride) will be replaced if possible.
Sodium fluoride(toothpaste grade/food Grade)
Basic Information
Product name:Sodium fluoride
CAS No:7681-49-4
Molecular formula::NaF
Other name:Sodium fluoride(toothpaste grade/food Grade)
Molecular weight: 41.99
Appearance and character
white powder/crystal.
Application:
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.

Operational notes:
Closed operation, local exhaust. Operators must be specially trained to strictly follow the operating procedures. It is recommended that the operator wear a hood-type electric air filter type dust-proof respirator, wear a tape anti-drug, and wear latex gloves. Avoid dust. Avoid contact with acids. Lightly load and unload during handling to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.
