| Methods and Procedures | ||||||||
| Fineness | All the above formulations exhibited a fineness of grind below 15 μm. | |||||||
| Viscosity | The 6070 and the 6070:6272 (1:1) blend formulations appeared more fluid, while the others appeared more viscous. (Note: This is a visual observation and may be influenced by material characteristics.) |

| Viscosity ranking | 6070≈6070：6272（1：1）＜6270A≈6272 | |||||||
| Fineness | The 6270A formulation turned gritty, while all other formulations met the fineness specification of <15 μm. | |||||||
| Conclusion | ||||||||
1. Dispersant 6070 demonstrated good viscosity reduction in the Phthalocyanine Blue paste. 2. After accelerated storage, the formulation exhibited a degree of thixotropy. |
