UV 365nm pigments uv fluorescent pigment for anti-falsification
Introduction UV fluorescent pigment itself is colorless, and after absorbing the energy of the ultraviolet light (uv-365nm or uv-254nm), it rapidly releases energy and exhibits a vivid color fluorescent effect. When the light source is removed, it stops immediately and back to the original invisible state. Directions for use Item Application 365nm organic 365nm inorganic 254nm inorganic Solvent based: ink/paint √ √ √ Water based: ink/paint X ... -

Sunlight Sensitive Coating Dye For Photochromic Lenses
Introduction: 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 ... -
