According to the experimental results, the JF2N series can greatly reduce the subsequent thickener dosage.
It also exhibits excellent anti-sagging performance even with a very short flow time measured by a #3 cup at the application viscosity.
In this experiment, a conventional talc and a medium-to-high-end talc were used for comparison.
These two talc products have slightly lower oil absorption and lower initial viscosity during paint preparation,
resulting in higher thickener consumption in subsequent steps.
Moreover, under the same water addition, their #3 cup flow time is longer during application.
Excessive thickener addition tends to cause post-thickening.
Therefore, the JF2N series talc is more suitable for this system.
Heat Storage Stability Test
Polyurethane Slurry Formulation:
• After storage at room temperature for 3 days,the conventional talc showed severe hard settling,while the two JF2N talc samples exhibited almost no change.
• After heat storage for 6 days in the polyurethane formulation, as shown in the figure:
Experimental Conclusion:
1. In terms of the thickening effect in the pre-slurry, the JF2N control group is significantly superior to conventional talc.
2. In terms of anti-sagging performance, the JF2N control group is significantly better than conventional talc, with a very obvious effect.
4.In terms of corrosion resistance, JF2N talc outperforms the blank group in water resistance, salt spray resistance tests, and alkali resistance tests in the epoxy formulation.
5. In the polyurethane formulation, after storage at room temperature,conventional talc shows severe hard settling,while JF2N only has soft settling with no effect after stirring
