Photochromic Powder/Thermochromic Powder Series

1.?Photochromic powder is a photosensitive material, which is a raw material coated with photosensitive pigments. The photosensitive pigments are materials that undergo reversible color changes under sunlight/ultraviolet light. When irradiated by light, they undergo molecular structure changes, causing color changes. When the light is removed, they return to their original color.
2.?Thermochromic powder is a pigment whose color changes due to chemical structure changes caused by heat. Thermochromic products have the characteristic of changing from colored to colorless when the temperature rises to a specific active temperature (such as 28°C, 31°C, etc.).
