BARIFINE Ultrafine Barium Sulfate
Barium sulfate is a substance that features high heat resistance, chemical resistance, water resistance, and chemical stability.
BARIFINE, the world’s smallest particle size barium sulfate, demonstrates superior transparency when added to resin and provides a variety of other effects.

1.Transparency
Thanks to its small particle size (0.01-0.1 µm), BARIFINE provides superior transparency compared to general barium sulfate when sufficiently dispersed, allowing for use as a transparency extender pigment.

2.Improves the jet blackness of carbon black
Dispersing BARIFINE together with carbon black lets BARIFINE act as a medium to break up the clumping of carbon black. This medium effect allows for improved jet blackness and reduced dispersion time.

3.Better color development, coating film gloss, and smoothness of organic pigments
Adding BARIFINE promotes the dispersion of organic pigments for better color development and gloss of coating film.
