Experimental Method
1.Stir for 10 minutes and record the viscosity.. 2.Add the aqueous polyurethane resin at a resin-to-filler ratio of 3:7, and stir for 5 minutes. Record the viscosity.
Test Result
Resin-Free Paste Viscosity（mpa.s ）
34℃	6220	6210	6070	Note		Stand for 24 hours
Calcium Carbonate	109	472	100	Dispersants 6210 and 6070 showed significant foaming		Dispersants 6220 and 6070 formed a hard sediment
Talc	833	1830	67.1	Dispersants 6220 and 6210 showed significant foaming		Dispersant 6210 resulted in a soft sediment, whereas 6070 produced a hard sediment.
Aluminum Hydroxide	78.5	449.6	495.2			Dispersants 6220 and 6070 formed a hard sediment
In the resin-free paste, dispersant 6070 demonstrated the best viscosity reduction with calcium carbonate and talc, while 6220 was most effective with aluminum hydroxide
Resin Paste Viscosity（mpa.s ）
34℃	6220	6210	6070	Note
Calcium Carbonate	30	282	23.3
Talc	766.3	268	10
Aluminum Hydroxide	8.9	472	6.7
In the polyurethane-based paste,dispersant 6070 demonstrated the best viscosity reduction.
Conclusions
In the aqueous resin-free paste, dispersant 6220 provided the overall best performance in viscosity reduction. In the aqueous polyurethane dispersion-based filler paste system, dispersant 6070 provides good viscosity reduction.
