We aim to “repaint the world” with new color materials - silicon nanoparticles. They will not only introduce new color design, but will also have a significant impact on reducing CO2 emissions by contributing to weight reduction and resource conservation in mobility. We will produce and sell an innovative color material that enables the world’s lightest-weight color paints, ideal for use in mobility paints and cosmetics applications. Mie-resonant silicon nanoparticles generate vivid color with an extremely small amount of material.While conventional pigments typically require coatings thicker than 20 micrometers, our material achieves the same visual impact with just 200 nanometers — 100 times thinner than traditional coatings. This ultra-thin structure unlocks new possibilities in color application, material efficiency, and sustainability.
