The tinting strength can also be defined as the relative power of coloring a paint, coating, or ink system. This is also referred to as tint color. The higher the tinting strength the higher will be the reduction of the whiteness (Rutile or TiO 2) of the paint. In many cases, the tinting strength is also relative to the opacity of the paint or ...

Attrition mills are more appropriate for "midrange" size particles. Such mills utilize 310mm media to produce material ranging in size from approximately 1 to 10 microns. The first "small media" mill was introduced about 60 years ago. It was named a "sand mill" because it used 1/641/8 in. Ottawa silica from Canada.

The different types of wetting and dispersing agents are described in Table 1. Wetting. To properly wet a pigment, the air/solid interface needs to be replaced by a liquid/solid one. Therefore, the less air entrapped in the system, the more effective the wetting will be. It's all about surface tension!

In the industry, the fineness of grind is generally achieved with a 2step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.
