By precisely controlling the coating thickness of titanium dioxide, the iridescent series produces gold, red, purple, blue, green and other rainbow-like interference-changing colors, and gives luster. The color of this series is completely caused by the interference of physical light.
The optical path difference between the reflected light of the high refractive index titanium dioxide and the reflected light of the low refractive index mica causes interference and exhibits different colors, does not contain any pigment, but has a strong color density. In addition, the titanium dioxide crystal form of this series is rutile.
Therefore, it has good stability, no fading, no color migration, and the like, and also has good weather resistance. This series of products also produces rich and brilliant pearlescent effect due to different background colors or color matching with organic pigments.
