Do I need to consider the particle size when choosing copper mica powder pigment?

When selecting copper mica powder pigments, particle size is a very important factor to consider.
Firstly, the size of pigment particles directly affects their coloring power and saturation. Generally speaking, pigments have small particle size, large specific surface area, high coloring power, and good saturation; On the contrary, larger particle size, smaller specific surface area, lower coloring power, and lower saturation.
Secondly, particle size also affects the heat and light resistance of pigments. Small pigment particles have a larger specific surface area, therefore their light resistance is relatively poor. Pigments with larger particle sizes usually have better heat resistance.
Finally, particle size also affects the dispersion and adhesion of pigments in the coating. The smaller the particle size of mica powder, the better its dispersion and adhesion in the coating.
Therefore, when selecting copper mica powder pigments, it is necessary to consider the impact of particle size on pigment performance based on specific application scenarios and requirements, and select suitable particle size specifications.
