The production of pearlescent pigments is a very fine chemical processing process, and the quality requirements of the products far exceed the requirements for conventional inorganic materials and general fine chemical products. Not only the high purity and less impurities of the product are required, but also for the white pearlescent pigment, the product has high whiteness and brightness.

For colored pearlescent pigments, the product is required to have a very pure hue and a high color saturation. The quality index of the product such as light resistance, weather resistance, chemical corrosion resistance is the highest level of all inorganic and organic pigments.

In addition, there are quite high requirements on the properties of the pigments. For example, pearlescent pigments should have good moisturization, dispersibility and certain hiding power in organic solvents and resins of different polarities, and it has good compatibility with transparent organic pigments and dyes.

For pearlescent pigments used in food, pharmaceutical packaging, children's toys, and cosmetics, there are very strict requirements for heavy metal ions and microbial content. These are the differences between general fine chemical products and inorganic functional materials.

Pearlescent pigments, especially mica titanium pearlescent pigments, require a very complex production process from raw materials to product storage. Such as mica sorting, impurity removal, grinding, grading (rough grading and precision grading), surface activation treatment, hydrolysis, filtration, washing, drying, calcination, post-treatment, secondary drying, etc. There are many factors that affect product’ s quality, and each process must strictly control various process parameters.

The production process of pearlescent pigments can be said to be very precise, and each process must be strictly carried out in order to obtain the final pearlescent effect.
