980nm IR fluorescent pigment Anti-Counterfeit Pigment
TopwellChem’s Infrared Fluorescent Pigment IR980 Green utilizes nano-scale rare earth materials to generate high-intensity green fluorescence strong (emission wavelength 520-550nm) under 980nm NIR excitation. Featuring exceptional environmental stability through advanced coating technology, it withstands temperature extremes (-40℃~260℃), UV radiation, and common chemical solvents. Compatible with multiple substrates including <strong>inks/coatings/plastics, maintaining over 98% fluorescence intensity after curing.
Certified by ISO9001,SGS, available in 5-20μm customizable particle sizes. Its unique covert anti-counterfeiting properties excel in security printing for banknotes, ID documents, and luxury packaging, enabling three-tier authentication with dedicated detectors. Laboratory tests show less than 3% fluorescence attenuation after 1000-hour continuous illumination, making it ideal for industrial-grade long-term marking.

Universal characteristics
Infrared excitation ink/pigment: Infrared excitation ink is a printing ink giving off visible, bright and dazzling light (red, green and blue) when exposed to infrared light (940-1060nm). With the features of high technology content, difficulty in copying and high anti-forgery capability, it can be applied in anti-forgery printing widely, especially in RMB notes and gasoline vouchers.
Product characteristics
1. Photoluminescent pigment is a light-yellow powder, turns to yellow green, blue green, blue, and purple etc colors after being excited by light.
2. The smaller the particle size, the lower the luminance is.
3. Compared with other pigments, photoluminescent pigment can be easily and widely used in many fields.
4. High initial luminance, long afterglow time (Test according to DIN67510 Standard, its afterglow time can be 10, 000 minutes)
5. Its light-resistance, aging-resistance and chemical stability are all good (more than 10 years of life span)
6. It is a new type of environmentally friendly photoluminescent pigment with the characteristics of non-toxicity, non-radioactivity, non-flammability and non-explosibility.
