Pigment alkali resistance

The alkali resistance of a pigment refers to whether the pigment coating can remain stable in an alkaline environment. It is usually necessary to test the alkaline Stability of the pigment and the alkali resistance of the coating. To detect the alkali resistance of the pigment, you can use the alkaline solution immersion test, place the pigment or coating in the alkaline solution for a period of time, and then evaluate whether its performance changes; at the same time, you can also observe the performance of the coating in the actual alkaline environment, such as whether flaking or blistering occurs.
