Recommended Mixing Equipment for Pigment Dispersions

Pigment dispersions are typically prepared in a two-step process: (1) powder wet-out in a batching tank and (2) one or more passes through a mill to achieve the desired fineness of grind. The costly and time-consuming milling step is often a production bottleneck which in the past has forced manufacturers to add more milling equipment to handle ...

Pigment concentrates - BYK

Pigment concentrates (pigment pastes) are monopigmented systems with as high as possible pigment content and as little as possible binder (grinding resin). They are used in two ways in the production of coatings. For tinting: After the grinding and finalization, the pastes are used for the final fine adjustment of the color, i.e. for nuancing.
