Pigmentikäsittely

Pigmentikäsittely refers to processes or treatments applied to pigments to alter their properties. These modifications can aim to improve a pigment's performance, stability, dispersibility, or compatibility with various media. Common treatments involve surface coatings, chemical modifications, or particle size adjustments.

Surface treatments are frequently used to enhance a pigment's interaction with a binder or solvent. For example, applying a hydrophobic coating can improve dispersibility in oily media or water-repellent finishes. Similarly, surface treatments can increase lightfastness by protecting the pigment core from degradation. Chemical modifications might involve altering the pigment's molecular structure to achieve a specific hue, opacity, or chemical resistance.

Particle size control is another crucial aspect of pigment treatment. Grinding or milling processes are used to reduce particle size, which can influence tinting strength, gloss, and hiding power. Conversely, agglomeration processes might be employed to create larger, more uniform particles for specific applications.

The goal of pigmentikäsittely is to optimize pigments for their intended use, whether in paints, inks, plastics, cosmetics, or other applications. By tailoring the pigment's characteristics, manufacturers can ensure consistent color, durability, and ease of application in the final product. The specific treatment depends heavily on the pigment type and the desired end-use properties.
