    Fluorescent Glow Powder - Thermochromic pigment for thermochromic Paint Thermochromic Ink Thermochromic Fabric – Topwell

    Introduction Themochromic pigments are composed of micro-capsules that change color reversibly. When the temperature is raised to a specified temperature the pigment goes from colored to colorless (or from one color to another color). The color returns to original color as the pigment is cooled down.  Processing temperature The processing temperature should be controlled below 200 ℃, the maximum should not exceed 230 ℃, heating time and minimize material. (High temperature, prolonged heating...

  • Sunlight Uv Light Change Photochromic Pigment - Photochromic Dye for Optical Lenses Change Color From Clear to Grey Under Sunlight  – Topwell

    Sunlight Uv Light Change Photochromic Pigment - Photochromic Dye for Optical Lenses Change Color From Clear to Grey Under Sunlight – Topwell

    Photochromic Dyes are reversible raw dyes in crystalline powder form. Photochromic dyes reversibly change color upon exposure to ultraviolet light in the range of 300 to 360 nanometers. Full color change occurs in just seconds when using a flash gun to 20-60 seconds in the sunlight. The dyes change back to colorless when removed from the UV light source. Some colors may take longer to fade back to completely clear than others. Photochromic dyes are compatible with one another and can be m...
