Precipitated Barium Sulfate Safe Baso4 is superior to most other fillers, especially in chemical resistance coating. It is inert, insoluble in water, acid, alkali and organic intermediaries, excellent gloss and particle fineness, so that the topcoat can be protected in long-term exposure. Barium sulfate is recommended for topcoat, which can increase surface hardness and color stability.
