Comparative test of 75% water-based white paste dispersant

2026-01-27

EZHOU ANJEKA TECHNOLOGY CO.,Ltd professional additives supplier
Experimental record sheet
Test name	Comparative test of 75% water-based white paste dispersant					Temperature/humidity：	4-5/100
Customer	Qiyuan	Applicant	Mrs Xv	Test date	Jan.16 2026
Objective： In this system, the dispersants compared to BYK190 were screened and compared
color paste formula
color paste formula				Sedimentation Status After Storage
material	amount	note
water	18.8
dispersant	6	Anjiakang 6070, 6871, 6210, 6220 and BYK-190
defoamer	0.2	Anjeka5062A
titanium dioxide	75	sample from customer

Experimental Method
After the color paste is configured, disperse the color paste at a high speed of 2000r/min * 30min Place at room temperature to compare the fineness, viscosity, and settling state of the color paste after thermal storage“
Result
Initial Paste
Item	BYK-190	Anjeka6070	Anjeka6871	Anjeka6210	Anjeka6220
Fineness μm	≤20	≤20	≤15	≤15	≤25
Viscosity mpa.s	1130	1442	1754	2403	5119
Paste after Heat Storage at 54℃ for 2 Days
Item	BYK-190	Anjeka6070	Anjeka6871	Anjeka6210	Anjeka6220
Fineness μm	≤20	≤20	≤15	≤15	≤25
Viscosity mpa.s	385	2595	3365	2908	19804
Sedimentation Status	Small amount of hard sediment	A small amount of soft sediment	Slight thixotropy/No settling	Slight thixotropy/No settling	Thick/No settling

Experimental Conclusion
1. Dispersion Efficiency: 6871 and 6210 are superior to BYK-190. Anjeka-6070 shows comparable efficiency to BYK-190. 2. Viscosity Reduction: 6871 and 6070 are slightly inferior to BYK-190 in viscosity-lowering capability. 3. Thermal Storage Settling: 6871: No settling. 6070: Soft settlement (easy to redisperse). BYK-190: Hard settlement (difficult to redisperse).
