Photochromic powder is a special type of pigment that changes color when exposed to ultraviolet (UV) light, such as sunlight or UV lamps. When the UV light is removed, the powder gradually returns to its original transparent or light-colored state. This reversible reaction is due to the photochemical properties of the material, typically composed of organic compounds or silver halides embedded in a matrix.
UV-Activated: Changes color under UV light (e.g., from colorless to vibrant shades like blue, pink, or purple).
Reversible: Returns to its original state once UV light is removed.
Durable: Can be incorporated into plastics, inks, coatings, and textiles for long-lasting effects.
Temperature Sensitivity: Some types may respond differently based on ambient temperature.
There are two Series:
1. colored to colored
2. colorless to colored 
Smart Materials: Used in sunglasses, lenses, and windows that darken in sunlight.
Security Inks: For anti-counterfeiting in banknotes and documents.
Cosmetics & Nail Art: Creates color-changing makeup and nail polish.
Toys & Fashion: Adds dynamic effects to clothing, accessories, and novelty items.
Photochromic powder is widely valued for its innovative and functional properties in both industrial and creative fields.
Photochromic powder is a smart pigment that changes color when exposed to UV light (sunlight or UV lamps) and reverts to its original color indoors. It's widely used in coatings, inks, textiles, plastics, and DIY crafts.
The powder contains photochromic microcapsules that react to UV rays. When exposed to sunlight, the molecular structure shifts, causing a color change (e.g., colorless → blue). The process is reversible and repeatable.
Coatings & Paints: For walls, ceramics, or automotive parts.
Plastics: Injected or molded into toys, sunglasses, etc.
Textiles: Screen-printed on fabrics (e.g., T-shirts, bags).
Inks: For security printing or novelty products.
