Infrared pigment
【Introduction】
Infrared pigment is a luminescent material that can convert infrared or near-infrared light into visible light. It is commonly known as infrared excited phosphor. It is a rare earth inorganic substance whose main component is fluoride. It is an infrared display pigment and can also be called infrared powder. Specifically, it can excite visible light of red, yellow, blue, green and other colors when illuminated by infrared light with a main wavelength of 980nm. Products made with infrared excitation pigments are highly concealable and easy to identify authenticity. Therefore, they are used for anti-counterfeiting marks on packaging and printing products, as well as for identifying the authenticity of well-known tobacco and alcohol products, medicines, cosmetics, plastic toys and other products.
【Physical properties】
Appearance color: white or slightly reddish powder
Average particle size: ﹤10um
Density/specific gravity: 3.60g/ml
Melting point: ﹥950℃
Oil absorption capacity (DBP): 50-60 cm3/100g pigment
Thermal stability: ﹤500℃
【Application Features】
Infrared pigments specifically include four basic colors: red, yellow, blue, and green. Green powder emits the best brightness. This pigment has good weather resistance, high temperature resistance, acid and alkali resistance, solvent resistance, and is also insoluble in water.
When used in inks and coatings, high-speed dispersion and grinding are required. Depending on the thickness of the final coating, the addition amount is 5%--20%. When the coating is thin, the pigment needs to be added in a high amount. When used for plastic injection molding or extrusion, the addition amount is 0.2%--3%. （Infrared display pigment，Infrared-excited pigments）
