Does organic coloring mica powder pigment need to be properly stored if it is not used for a long time?

Organic colored mica powder pigments that are not used for a long time do need to be stored properly to ensure their quality and stable performance. Here are some storage suggestions:
Firstly, the storage environment should meet the conditions of dryness, coolness, and good ventilation. This is because high humidity may cause the pigment to become damp, clump, or deteriorate, while high temperature may accelerate the oxidation reaction of the pigment, affecting its color and stability. Therefore, choosing a suitable storage space is crucial.
Secondly, organic colored mica powder pigments should be stored in well sealed containers to prevent oxygen, moisture, and impurities from entering the air, thereby avoiding oxidation, fading, or contamination of the pigments. Meanwhile, containers should be made of non-metallic materials such as plastic or glass to avoid chemical reactions with pigments.
In addition, during storage, pigments should be avoided from being exposed to direct sunlight or strong light sources, as ultraviolet and other light may affect the color of the pigments, causing them to fade or discolor.
Finally, for pigments that have already been opened and used, they should be used up as soon as possible or stored in a properly sealed container. If the pigment clumps or dries, you can try gently stirring or adding a small amount of diluent to restore its fluidity, but be careful not to damage the color and structure of the pigment.
