In the ever – evolving world of specialty pigments, 365nm UV fluorescent pigments have carved out a significant niche, and among them, UV Red Y3B stands out for its remarkable properties and diverse applications.
A. Intense Fluorescence under 365nm UV Light
UV Red Y3B is engineered to emit an extremely intense red fluorescence when exposed to 365nm ultraviolet light. This wavelength is crucial as it is not only a common wavelength in UV – based detection systems but also provides an optimal excitation source for this pigment. The intense red glow is highly visible even in low – light or dark environments, making it an ideal choice for applications where high – contrast visual signals are required. For example, in UV – illuminated displays or signage, the red fluorescence of UV Red Y3B can attract immediate attention, ensuring that the intended message is conveyed effectively.
B. Invisibility in Daylight
One of the most unique features of UV Red Y3B is its complete invisibility under normal daylight conditions. This property makes it perfect for applications that require covert or hidden markings. In security and anti – counterfeiting applications, for instance, documents such as passports, banknotes, or high – value product labels can be marked with UV Red Y3B. These markings are invisible to the naked eye during normal handling, but when exposed to a 365nm UV light source, they reveal distinct red fluorescent patterns, providing an additional layer of security.
C. High Chemical Stability
UV Red Y3B exhibits excellent chemical stability. It can withstand exposure to a wide range of chemicals without losing its fluorescence properties. This makes it suitable for use in harsh environments or in combination with different materials. Whether it is incorporated into plastics, coatings, or inks, the pigment remains stable and continues to emit its characteristic red fluorescence under 365nm UV light. For example, in industrial applications where materials are exposed to chemicals during processing or use, the chemical stability of UV Red Y3B ensures that the fluorescent markings or features remain intact.
D. Good Thermal Resistance
The pigment also shows good thermal resistance. It can endure high temperatures during manufacturing processes such as extrusion, injection molding, or curing of coatings and inks. This thermal stability allows it to be used in a variety of applications that involve high – temperature processing. For instance, in the production of fluorescent – marked plastic components, the pigment can withstand the high temperatures associated with plastic extrusion, ensuring that the final product has consistent and reliable fluorescence properties.
E. Fine Particle Size for Easy Dispersion
UV Red Y3B typically has a fine particle size, which enables easy dispersion in various media. Whether it is being mixed into liquid inks, resins for coatings, or polymer matrices for plastics, the small particle size ensures uniform distribution. This uniform dispersion is essential for achieving consistent fluorescence intensity across the entire product. In the production of fluorescent – coated surfaces, a well – dispersed UV Red Y3B pigment will result in a smooth and evenly – glowing finish, enhancing the aesthetic and functional aspects of the coated object.
II. Applications of UV Red Y3B
A. Security and Anti – Counterfeiting
- Document Security
- In the security of important documents like passports, visas, and identity cards, UV Red Y3B can be used to create hidden fluorescent markings. These markings can be in the form of patterns, logos, or text. When a 365nm UV light is shone on the document, the red fluorescent markings become visible, which can be used to verify the authenticity of the document. For example, border control officers can quickly check the authenticity of a passport by using a handheld UV light source to reveal the hidden UV Red Y3B – based security features.
- Banknotes also benefit from the use of UV Red Y3B. Central banks can incorporate this pigment into the printing ink of banknotes. The fluorescent markings can be designed in such a way that they are difficult to replicate, providing an effective anti – counterfeiting measure. Currency validators in banks are equipped with 365nm UV light sources to detect these red fluorescent features on banknotes.
- Product Authentication
For luxury goods and high – value products, UV Red Y3B can be used in the packaging or on the product itself for authentication purposes. Manufacturers can apply a small amount of the pigment in a hidden location on the product or its packaging. Consumers can then use a portable UV light to check the authenticity of the product. For example, high – end fashion brands may use UV Red Y3B in the labels or tags of their products, allowing customers to easily verify if the item is genuine.
B. Signage and Displays
1.Indoor and Outdoor Signage
In environments where visibility is crucial, such as in shopping malls, airports, or emergency exits, UV Red Y3B can be used in signage. When these signs are illuminated by UV – LED lights (emitting at 365nm), the red fluorescent color of the pigment makes the signs highly visible. In a shopping mall, for example, directional signs with UV Red Y3B – based markings can guide customers to different stores or facilities, even in crowded or low – light areas.
Outdoor signage in areas with high ambient light can also benefit from UV Red Y3B. During the day, the signs are inconspicuous, but at night, when illuminated by UV – based lighting systems, they stand out with their bright red fluorescence, providing important information such as wayfinding directions or safety warnings.

2.UV – Responsive Displays
In the field of display technology, UV Red Y3B can be used in UV – responsive displays. These displays can be used for advertising, interactive exhibits, or in some specialized electronic devices. When a 365nm UV light source is directed at the display, the areas with UV Red Y3B pigment will emit red fluorescence, creating dynamic and eye – catching visual effects. For example, in a museum exhibit, a UV – responsive display with UV Red Y3B can be used to highlight specific artifacts or information, enhancing the visitor experience.

C. Industrial and Quality Control
1.Plastic and Coating Inspection
In the plastics industry, UV Red Y3B can be added to masterbatches. During the manufacturing process of plastic products, any irregularities in the distribution of the pigment can indicate problems in the mixing or extrusion process. By using a 365nm UV light source, manufacturers can quickly identify areas where the pigment is not evenly distributed, ensuring the quality of the plastic products.
Similarly, in the coating industry, UV Red Y3B can be incorporated into coatings. After application, the coating can be inspected under UV light. Uneven fluorescence can signal issues such as poor coating thickness, incomplete coverage, or problems with the curing process. This helps in ensuring that the coated surfaces meet the required quality standards.

2.Leak Detection and Fluid Tracing
In industrial settings, UV Red Y3B can be used as a tracer in fluids. For example, in a pipeline system, a small amount of the pigment can be added to the fluid being transported. If there is a leak in the pipeline, the escaping fluid will leave behind a red – fluorescent trail when exposed to 365nm UV light. This makes it easy for maintenance crews to quickly locate and repair the leak, minimizing downtime and potential damage.
