2. Mold and Mildew Resistance By keeping surfaces dry, waterproof paint also helps to inhibit the growth of mold and mildew. These fungi thrive in damp conditions, and their presence can lead to health issues and structural damage.

Finally, mica's impact on China's economy cannot be overstated. By driving multiple industries and fostering technological advancement, mica has become a pivotal element in China's industrial narrative. It contributes significantly to export revenues, creating jobs and fostering economic stability. As such, mica is not just a mineral but a cornerstone of China’s sustained industrial growth and global trade dominance.

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.
