The cross-section of mica pigment has a physical structure similar to that of pearls; the core is mica with low optical refraction, surrounded by an outer layer of high-refraction metal oxides, such as titanium dioxide or iron oxide. Under ideal conditions, mica pigment is evenly dispersed in the coating, and forms a multi-layer distribution parallel to the surface of the material, just like in pearls, where the incident light experiences multiple reflections and interference to create the mica effect. With the development of mica pigment production, its application is becoming increasingly well-known. It can be used in automotive, motorcycle, bicycle coatings, powder coatings, architectural coatings, mica inks, mica plastic products, mica cosmetics, and can also be applied to the paper, dyeing and printing, rubber, ceramics and other industries.
