The Iridescent Series achieves rainbow-like interference-shifting colors in gold, red, purple, blue, and green, while also imparting a lustrous sheen by precisely controlling the coating thickness of titanium dioxide. The colors of this series are entirely due to the physical phenomenon of light interference.
The optical path difference between the reflected light from the high-refractive-index titanium dioxide and the low-refractive-index mica creates interference, resulting in distinct colors. While free of any pigment, these products possess a high degree of color concentration. Furthermore, the titanium dioxide in this series is all rutile, resulting in excellent stability, resistance to fading, color migration, and weathering resistance. These products can also produce a rich, vibrant pearlescent effect when used with different base colors or when combined with organic pigments.
