Experiment Record Sheet
Experiment Name	Viscosity reduction of MA-100 vinyl chloride-vinyl acetate resin black paste					Temperature / Humidity	23°C / 94%
Customer	/	Applicant	/	Experiment Date	25-Jun-26
Objective: Screen suitable dispersants with lower viscosity than the reference dispersant 3250, while maintaining consistent color development. The sample resin has very high viscosity — three-roll mill grinding is required for viscosity reduction.
Pigment Paste Formulation
MA-100 Vinyl Chloride-Vinyl Acetate Resin Black Paste
VAc resin	84
Dispersant	3	3250	6110S	6915	26062910

Method
Formulate materials with different dispersants according to the procedure. Add glass beads and disperse at 1800 r/min for 20 minutes using a disperser, with fineness ≤ 15 μm. Measure viscosity and compare color development.
