365nm Inorganic UV Fluorescent Yellow-Green Invisible Security Pigment Powder
Nichwell’s 365nm inorganic UV fluorescent yellow-green pigment is a highly stable, industrial-grade luminescent material designed for high-end optical security applications. In invisible daylight or regular indoor lighting, the powder remains an off-white, inconspicuous shade. However, once exposed to a long-wave ultraviolet light source at 365nm, it instantly transitions into a vivid, intense fluorescent yellow-green glow.
Technical Features & Advantages
Superior Heat Stability: Capable of withstanding extreme temperatures (up to 400°C), making it perfectly suited for high-temperature plastic injection molding and masterbatch processing.
Excellent Lightfastness & Weatherability: Highly resistant to UV degradation and outdoor weathering, ensuring long-lasting fluorescence without fading.
Outstanding Solvent Resistance: Formulated to remain inert and stable in various aggressive organic solvents, acid, and alkali environments—ideal for complex chemical ink formulations.
- Inconspicuous Daylight Body Color: Provides high concealment in security printing applications, ensuring the print remains hidden until verified under a 365nm UV blacklight.
365nm Inorganic UV Fluorescent Pigment 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.
