We offer calcium fluoride nanoparticles dispersed in a variety of media. They can be used as durable remineralizing agents in dental composites and dental varnishes where their bioactivity is due to calcium and fluoride ion release. They are compatible with all dental monomers. Our calcium fluoride dispersions can also be used to produce low refractive index coatings with high light transmission and mechanical resistance. The refractive index of calcium fluoride is significantly lower than that of metal oxides, and its optical window is considerably wider. Main benefits - Smallest CaF2 particles on the market - High solid content - High transparency of dispersions - High translucency of dental composites - High depth of cure of dental composites Samples and Safety Data Sheet are available.
