[Product description]
The 365nm organic UV purple fluorescent pigment UV Purple Y3A is designed based on pure organic compounds. By absorbing 365nm ultraviolet light to stimulate electron transition, it releases red visible light with longer wavelength , and its fluorescence intensity can be more than twice that of ordinary pigments, which significantly improves the visual impact.
Core features: High compatibility: Perfect compatibility with UV curing resin, ink, coating and other systems, suitable for free radical or cationic polymerization system, without affecting curing speed and final mechanical properties.
Accurate excitation: specially optimized for 365nm wavelength, matched with mainstream UV-LED light sources (such as Futanxi UV-LED surface light sources) to achieve high-efficiency energy conversion and deep excitation.

Environmental protection and safety: it contains no heavy metals (such as cadmium and lead), meets RoHS and REACH standards through skin irritation and toxicity tests, and is suitable for consumer goods and packaging fields.

[Application]

Low dosage: only 0.1%-0.5% dosage is needed to achieve remarkable fluorescence effect and reduce the formulation cost.

Multifunctional: support transparent or translucent substrate, suitable for surface coating, embedded mark and 3D printing structure.

Use the scene has been widely used in the following fields due to its unique fluorescence characteristics and light response ability:

Anti-counterfeiting and safety identification

Invisible marks used for currency, documents and luxury goods packaging can quickly identify the authenticity through 365nm ultraviolet light.

Detection of invisible defects in industrial parts (such as PCB), fluorescence reaction can locate microcracks or residual pollutants.

Smart Materials and 4D Printing

It is integrated into photocurable resin, and the curing degree is monitored by real-time red light intensity change (such as phosphorescence monitoring technology developed by East China University of Science and Technology) to optimize 3D/4D printing process.

In dynamic deformation materials (such as “flower opening and closing” structure), the fluorescence signal synchronously reflects the deformation stage, which improves the interactive visualization of smart materials.

Creative Design and Consumer Goods

Enhance the visual effect in art coatings, luminous toys and fashion accessories, and present dazzling red light at night or under ultraviolet environment.

Stage lighting and theme park decoration create an immersive light and shadow experience.

Industrial inspection and quality control

Combined with machine vision system (such as CCS UV light source), it is used for curing detection of electronic component packaging glue and sealing verification of drug packaging to improve detection accuracy and efficiency.

Biological and medical applications

Exploratively used in photodynamic therapy or biomarker, with strong red light penetration and low tissue damage, it may be extended to the field of medical imaging in the future.
