product

UV fluorescent pigment is invisible in regular light with colorless effect, it is visible in UV light with four basic colors, blue, green, yellow, red, as per this property, it can be used for security protection ink making, widely used on bank notes and certificates, labels etc.

[Application]

I. Anti-Counterfeiting and Security Applications

1. Advanced Anti-Counterfeiting Printing
   1. Currency/Documents:
      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.
   2. 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 Safety Markings
   1. Emergency Guidance Systems:
      Coated on fire equipment location markers and escape route arrows. Emits intense blue light when exposed to UV light during power outages or smoke-filled environments to guide evacuation.
   2. Hazard Zone Warnings:
      Applied to critical areas like chemical plant pipe joints and high-voltage equipment to prevent operational errors during nighttime work.

• II. 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.
  • Equipment Cleanliness Monitoring: Added to cleaning agents; residual grease/dirt fluoresces under UV to ensure sanitation in pharmaceutical/food production lines.
    Material Uniformity Analysis
  • Plastic/Coating Dispersion Testing: Incorporated into masterbatches or coatings. Fluorescence distribution indicates mixing uniformity for process optimization.
    

III. 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).
• Luminous Apparel/Accessories: Textile prints/footwear decorations maintaining fluorescence intensity after 20+ washes.
  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.
  

IV. Biomedical Applications
Diagnostic Aids

• Histological Staining: Enhances microscopic contrast by fluorescing specific cellular structures under 365nm excitation.
• Surgical Guidance: Marks tumor boundaries for precise excision under intraoperative UV illumination.
  Biological Tracers
• Eco-Friendly Tracers: Added to wastewater treatment processes; fluorescence intensity monitors flow paths/diffusion efficiency, eliminating heavy metal contamination risks.
  

V. Research & Specialized Fields
Electronics Manufacturing

• PCB Alignment Marks: Printed on circuit board non-functional areas; recognized by 365nm UV lithography systems for automatic exposure alignment.
• LCD Photoresists: Serves as photoinitiator component responsive to 365nm exposure sources, forming high-precision BM (Black Matrix) patterns.
  Agricultural Research
• Plant Stress Response Monitoring: Crops with fluorescent markers display color under UV light, visually indicating stress reactions.
