Micronized Barium Sulfate
Main applications
Powder Coatings, Industrial Paints, Protective Coatings, Plastics & Polymers
Overview
Micronized barium sulfate is a dense, white, chemically inert mineral filler. It is milled to a fine, controlled particle size for applications where surface quality matters.
In powder coatings and industrial paints it can contribute to surface smoothness, gloss and chemical resistance. Its low oil absorption limits binder demand. In plastics it adds density and can contribute to surface finish.
Main characteristics
- High specific gravity
- Chemically inert and insoluble in water
- High brightness
- Low oil absorption
- Fine, controlled particle size distribution
