365nm Inorganic UV Fluorescent White Pigment – High Stability Anti-Counterfeiting Material

365nm inorganic UV fluorescent white pigment is an inorganic functional fluorescent material that exhibits invisible or light-colored state under natural light, and emits bright, stable white fluorescence under 365nm long-wave UV light excitation.

Compared with organic fluorescent pigments, it features ultra-high weather resistance, light resistance, heat resistance, and long-term durability, making it widely used in outdoor anti-counterfeiting, security printing, plastic masterbatch, coating, and industrial identification fields.

Specification:

365nm inorganic uv fluorescent pigment unlike organic counterparts, these pigments are highly resistant to heat (withstand temperatures up to 300–800°C, depending on composition), light, and chemicals. They maintain fluorescence intensity even after long-term exposure to uv radiation, moisture, or harsh solvents, making them suitable for outdoor or high-temperature processing.

365nm UV Fluorescent Pigment Application:

1.Advanced Anti-Counterfeiting Printing

Currency/Documents
365nm uv fluorescent pigment can be used in banknote security threads and invisible markings on passport/visa pages. Displays specific colors (e.g., blue/green) under 365nm UV light, invisible to naked eye but detectable by currency validators. Provides strong anti-replication properties.
Product Authentication Labels:
Micro-dosed pigments incorporated into pharmaceutical packaging and luxury goods labels. Consumers can verify authenticity using portable UV flashlights, offering low cost and user-friendly operation.

2.Industrial Inspection & Quality Control

Non-Destructive Testing & Cleaning Validation
Metal/Composite Crack Detection: Used with penetrants that seep into cracks, fluorescing under 365nm UV light with micron-level sensitivity.
Material Uniformity Analysis Plastic/Coating Dispersion Testing: Incorporated into masterbatches or coatings. Fluorescence distribution indicates mixing uniformity for process optimization.

3. Consumer Goods & Creative Industries

Entertainment & Fashion Design
UV-Themed Scenes: Invisible murals in bars/body art at music festivals, revealing dreamlike blue effects under blacklights (365nm).
Toys & Cultural Products
Educational Toys: “Invisible ink” in science kits; children reveal hidden patterns with UV pens for fun learning.
Art Derivatives: Limited-edition prints with concealed layers activated by UV light for special visual effects.
