Anjeka Dispersant
Project: Dispersant Comparison
Category: Dispersant Testing
Personnel: R&D Department
Date Submitted: May 28, 2025
1. Objective
To compare the viscosity reduction effectiveness of different dispersants in a solvent-free, polyether polyol-based ground calcium carbonate (GCC) filler paste system.
2.Procedure
Prepare individual pastes using the following Anjikang dispersants:
6500
6402 (100%)
802
6501A
6976
6860
Compare the viscosities of the resulting pastes to evaluate dispersant performance.
3.Result and Discussion
3.1Method
Prepare the polyether polyol paste according to the formulation and process detailed in Table 1. Measure the viscosity after the paste has cooled to ambient temperature.,
3.2 Performance Testing
3.2.1Formulation
Table 1. Formulation of Polyether Polyol Paste
| Amount | Remark | |
| Polyether Polyol | 34.5 | PPG-3000 |
| Dispersant | 0.5 | Anjeka Dispersant |
| Ground Calcium Carbonate | 65 | 600 - 800 mesh |
| Total | 100 |
According to the formulation in Table 1, add the polyol and dispersant to the mixing vessel. Begin mixing at 500 rpm for 5 minutes. Slowly add the filler to the mixture, then increase the speed to 2500 rpm and disperse for 10 minutes. Once the temperature of the mixture has decreased to room temperature, measure the final viscosity.
