Sodium Monofluorophosphate (CAS 10163-15-2), also known as disodium fluorophosphate or SMFP, is a fluoride salt in the Salts & Minerals category, supplied as a white, odorless crystalline powder that serves as an anti-caries agent in oral care products and a corrosion inhibitor for reinforced concrete. Unlike standard fluorides, it offers exceptional compatibility with calcium-based abrasives, ensuring stability in toothpaste formulations.
In the construction sector, this white, odorless powder functions as a highly effective corrosion inhibitor for reinforced concrete structures. It penetrates concrete pores to protect steel rebar from oxidation, significantly extending the service life of infrastructure.
We supply Technical Grade and USP/Food Grade material that meets rigorous safety and quality standards for industrial processing. Its superior solubility and neutral pH profile make it a versatile ingredient for specialty chemical applications.
