TopwellChem’s Infrared Fluorescent Pigment IR980 Yellow is an innovative functional material, which uses nano-inorganic composite technology to realize the accurate matching of near-infrared excitation wavelength of 980nm and high brightness fluorescence emission.

Under natural light or general illumination, the pigment appears bright yellow; When irradiated by 980nm infrared light source, it can instantly activate its fluorescence characteristics and emit a unique signal that is invisible to the naked eye but can be clearly captured by professional equipment (such as infrared camera and night vision device).

• Anti-counterfeiting and security printing Currency/certificate/luxury label: printed invisible code, which can only be read by authorized equipment, so as to prevent counterfeiting. Drug packaging: embedded with infrared fluorescent anti-counterfeiting layer to ensure the transparency and traceability of the supply chain.
• Industrial detection and automation Identification of precision parts: spray invisible marks on the surfaces of automobiles and electronic components, and cooperate with infrared sensors to realize automatic sorting and quality traceability. Concealed marking of pipelines/cables: used for undisturbed positioning and maintenance records of complex facilities.
• Military and security Hidden military target: In night training or combat, the target position can only be identified by night vision equipment. Safety zone marking: set infrared visible path indication in confidential places to avoid naked eye exposure risk.
• Creative design and art Art of interactive installation: combine infrared interactive equipment to create a double visual experience of “visible light+hidden light effect”. Special effect paint: used for stage scenery or theme parks to enhance the immersive light and shadow effect.

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.
