Super Fine Lab Barium Sulphate Powder can also reduce the VOC of black coatings. The biggest effect here is that there is a great difference in oil absorption and specific surface area between carbon black and precipitated barium sulfate. Through anti flocculation, the effective effect of carbon black can only be slightly increased, while replacing a large amount of carbon black with precipitated barium sulfate will reduce the total base material demand and viscosity, and then reduce VOC.
