Grinding Pigment Dispersing

On the other hand, a resting of pigment/binder premixes prior to their dissolving or grinding helps to accomplish the wetting stage and always eases and accelerates dispersing processes. Grinding stage. After the wetting stage, it is necessary to de-aggregate and deagglomerate the pigment particles

    A friend recently wanted to know about pigment grinding, which made me realize that I had better begin this article by saying that we do not grind pigments, we disperse them. A bag of pigment contains clumps that must be separated into smaller clumps or individual particles. This is necessary in order to produce paint that provides good
