Preparation And Use Of Composite Inorganic Colored Pigments

The quality and performance of consumer and industrial products, as well as the requirements for appearance and durability, are constantly improving; As a result, considering the ecological aspects of the product, the demand for more durable but cost-effective pigments has steadily increased.

Complex inorganic pigments are becoming increasingly important for formula designers by optimizing the well-known chromium and nickel titanium yellow chemistry, providing a versatile tool for preparing economical, stable, and innovative coatings in various colors (from yellow to green, blue, and black). It is based on metal ions such as zinc, iron, titanium, nickel, cobalt, manganese, trivalent chromium, and antimony, which safely exist in stable lattices.

Replacing organic pigments can achieve higher coating coverage, as their extremely low oil absorption may result in higher pigment loading. Therefore, it is often used in combination with organic pigments to create bright colored coatings, such as for lead-free topcoats.

Due to their light resistance, high temperature resistance, chemical resistance (including acid and alkali), and weather resistance, they are also particularly suitable for coatings that must meet high durability standards. These include, for example, powder coatings and coil coatings, baking paints, as well as plastic and external building products such as cement, concrete, roof particles, and ceramic applications.
