How does sodium monofluorophosphate work?
There are many action mechanisms according to sodium monofluorophosphate uses.
The details are as following:
Its efforts in toothpaste:

The mechanism of action of sodium monofluorophosphate is mainly through the release of fluoride ions to enhance the resistance of teeth, inhibit the occurrence of dental caries, and have a certain bactericidal effect. Click to know its efforts by reading “sodium monofluorophosphate used in toothpaste”.
Cement corrosion inhibitor:
It inhibits both cathodic and anodic electrochemical processes in steel reinforcement. It is capable of causing a negative shift in the corrosion potential of concrete reinforcing steel bars, thus protecting to the bars. The kinetic potential polarization curves and electrochemical impedance spectra revealed that the addition of Na2PO3F can significantly change the corrosion behavior to the bar.
SMFP can form of a protective film on the surface of the steel bar, which is effective in blocking the erosive ions, for example, the chlorine ions.
Special glass manufacturing:
The mechanism of sodium monofluorophosphate is mainly in the following aspects:
Enhance the stability of glass:
The addition of MFP can enhance the chemical stability and thermal stability of special glass,thus improving the durability and service life of glass.
Improvement of optical properties:
It helps to improve the optical properties of special glass. By adding an appropriate amount of sodium monofluorophosphate, the refractive index and color of the glass can be adjusted to give it better optical properties and decorative effects. Then it is of a widely usage for the glass in optical instruments, glasses, and other fields.
Antibacterial and anticorrosive:
Sodium Monofluorophosphate also has antibacterial and anticorrosive effects, which is especially improve the hygiene and service life of the special glass.
Replacement of traditional ingredients:
The sodium monofluorophosphate can replace traditional ingredients, such as sodium fluoride, to provide better performance and a wider range of applications.

Herbicides and insecticides:
Sodium monofluorophosphate is mainly used in agriculture. It kills insects by disrupting the biochemical pathways of certain insect enzymes.
Addintivies:
It is also used in other areas, such as in wood and pulp processing as a bleaching agent and preservative, and as an additive in industries such as paints, plastics and cosmetics.
Conclusion
Above the action mechanism of sodium monofluorophosphate when it comes to use. Basicly speaking, the action mechanisms are results of the sodium monofluorophosphate chemical reaction. These action mechanisms not mentioned within this article could be deduced from the reaction factors too.
