UV Invisible yellow fluorescent pigment
[Product Name]UV Fluorescent Yellow Pigment
[Specification]
| Appearance under sunlight | Off white powder |
| Under 365nm light | Yellow |
| Excitation wavelength | 365nm |
| Emission wavelength | 544nm±5nm |
This pigment integrates seamlessly with anti-counterfeit inks, enabling the creation of invisible markings that are easily verified with common UV detectors (e.g., money counters). Its micron-level sensitivity in industrial testing ensures accurate crack detection in metals and cleanliness validation in pharmaceutical/food production. The fluorescence remains intense even after repeated washes in textile applications, highlighting its durability for consumer goods. Compliance with international safety standards further solidifies its role in critical sectors like biomedical diagnostics and food safety.
