Experiment Name	Replacement of Dispersant Tego 755W in PVC Ink Pigment Paste					Temperature / Humidity：
Customer	/	Applicant	/	Experiment Date
Objective: After 7 days of hot storage, compare with competitor product 755W: fineness must not show significant coarsening, and no hard sedimentation. Color development should also be evaluated before and after hot storage. Two formulations will be tested: one with deionized water and one with ethanol.
Pigment Paste Formulation
PVC INK
Water-Based Formulation				Ethanol-Based Formulation
Deionized Water	69.5			Ethanol	70
Anjeka7414	0.5			Carbon Black (sample)	20
Carbon Black (sample)	20			Dispersant	10	755W/6871/ 6071
Dispersant	10	755W/6871/ 6071

Test Method: Add test materials step by step, grind for 3 hours, then compare fineness, viscosity, and color development. Ethanol Resistance Test of Pigment Paste: Add 1 part of water-based pigment paste to 30 parts of ethanol, mix well, and observe for flocculation / coarsening.
