| Experimental Methods | ||||||||
| 1.Prepare the color paste batches according to the specified formulations. 2.Add 1.2 times the volume of glass beads and shake the mixtures for 3 hours using a paint shaker. 3.Measure the fineness of grind. Once it meets the specification, filter out the glass beads. 4.Measure the viscosity. 5.Draw down the paste and measure the jetness. |

| Jetness | 760W demonstrates the best jetness. The jetness of 6240 is comparable to that of 760W. As the other dispersants are of the same grade, the difference in jetness is minimal. | |||||||
