Determining the optimal dispersing agent loading

Composition of the pigment paste made up for subsequent testing of dispersion quality. After grinding, clear lacquers are pigmented with the prepared tinters and applied onto clean glass plates. The ratio of the pigment to binder solids should be as follows: Inorganic pigments = 20-30%. Organic pigments = 10-15%. Carbon black = 5-10%. 3).
