Photochromic MC Pigment

I. Product Overview Photochromic MC Pigment is a microcapsule pigment that undergoes reversible color change upon exposure to ultraviolet/visible light. Composed of a photochromic core material encapsulated in a wall, it is suitable for fields such as coatings, inks, and plastics, enabling dynamic color effects that change with light. II. Key Features · Reversible color change: Displays specific colors (e.g., blue, purple, red) under ultraviolet light, and reverts to the initial color (mostly colorless) when away from light. · Good weather resistance: Can undergo cyclic color change ≥5000 times, with a temperature resistance range of -30℃ to 80℃. · Easy to disperse: Microcapsules have uniform particle size, easily mixed into various substrates without affecting their processing performance. III. Common Specifications · Appearance: Microcapsule powder, particle size 1-10μm, color change response time ≤30 seconds. · Colors: Colorless → blue/purple/red/yellow, etc. (customizable), color fastness ≥ level 4. · Stability: Storage period ≥12 months (under dark and dry conditions), with good solvent resistance. IV. Typical Applications Anti-counterfeiting inks, color matching for toy plastics, outdoor coatings, sunglass lenses, clothing printing.
