The automotive industry has also embraced the use of mica pigment powder, particularly in paints and coatings. Mica’s reflective qualities provide a unique finish that enhances the appearance of vehicles. Paints containing mica can create a pearlescent effect, adding dimension and depth to car surfaces. This is particularly popular in high-end vehicles, where aesthetic appeal is paramount. Additionally, mica improves the durability and weather resistance of automotive paints, making it a practical choice for manufacturers looking to enhance both appearance and longevity.

Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.
