SODIUM SILICOFLUORIDE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Silicofluoride, also known as sodium hexafluorosilicate (Na2SiF6), is a white, crystalline inorganic compound used in various industrial and chemical applications primarily as a source of fluoride ions. In the water treatment industry, Sodium Silicofluoride is employed in water fluoridation programs to reduce the incidence of dental caries in communities. It is also used in the production of certain insecticides and pesticides, providing effective control of pests. In the chemical industry, Sodium Silicofluoride is used as a reagent in the synthesis of various organic compounds and as a flux in the smelting of metals. Proper handling and storage of Sodium Silicofluoride are essential to prevent moisture absorption and maintain its quality. It is generally considered safe for use in regulated amounts, although proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential to prevent irritation and other health hazards. Its versatility and effectiveness make Sodium Silicofluoride a valuable chemical in numerous applications.
