Sodium hexafluoroantimonate

Sodium hexafluoroantimonate (NaSbF6) is a fine chemical for deep processing of antimony, which is widely used as a catalyst in organic synthesis and photochemical reaction, and as an additive for high-grade glass. Additives for high-grade photocurable coatings and inks, pharmaceutical intermediates, material intermediates, etc. Especially in organic synthesis, it is usually used as a substitute for organic fluoride, and it is used in many scientific fields, from medicinal chemistry to material science, etc., all because pentavalent antimony forms a very strong coordination bond with fluorine ions, which makes fluorine in a very stable state.

Sodium hexafluoroantimonate is an indispensable additive for UV-curable coatings. UV-curable coatings have a bright future, and it is a rapidly developing “green” new technology. Since 1970s, the application of radiation curing technology has become more and more popular in developed countries. Compared with the traditional coating curing technology, radiation curing has the advantages of energy saving, no pollution, high efficiency, excellent performance, low investment in equipment and so on.

At present, as a “new technology facing the green industry in the 21st century”, photocuring technology has been widely used in many sectors of the national economy, and it has been well applied in paper, wood, plastic, metal, optical fiber and other substrates, with an amazing growth rate.

Sodium hexafluoroantimonate can also be used to replace organic fluoride in medicine. It has some unusual or even very special physical and chemical properties. This is because fluorine atoms are similar in size to hydrogen atoms, but they have great electronegativity. The introduction of fluorine will not cause obvious changes in the three-dimensional configuration of molecules, but will greatly change the electronic properties of molecules, which can be well used for various drug transformations and increase bioavailability. The strong pairing bond between pentavalent antimony and fluoride ion makes it very stable, has certain biological inertia, and does not participate in any biotransformation, so that it can be used as a pharmaceutical intermediate without any influence on organisms.
