CHAMELEON TP BLACK 31 Thermochromic microcapsule is product with a special thermochromic dye, which changes color according to temperatures. The thermochromic dye causes the change of color by the heat-induced chemical structure change. They are colored below an activation temperature and change to colorless or another color when reaching to activation temperature. The color change is reversible.

CHAMELEON UVC P-VIOLET Photochromic microcapsule is a microcapsule product with photochromic dye which changes its color by UV light. The photochromic dye causes color change reversibly by UVlight. When it is exposed to ultraviolet rays (sunlight), it causes color formation, and when the UV light is blocked, it turns to its original color. Since it is very sensitive to the externalenvironment, it becomes encapsulated in micro synthetic resin with several㎛ in diameter for protection and stability.
