| Experimental name: | 35% water-based resin-free black paste |
Temperature/humidity: | 3°C/86 | ||||
| Client: | / | Applicant: | Mrs Zuo | Experiment Date: | Jan.17,2026 | ||
|
Experimental objective: Screen and identify suitable water-based dispersants compatible with water-soluble resins. The key performance criteria are minimal change in fineness and viscosity after thermal aging, and the avoidance of gelling or hard settlement. |
