Textile: It can be used for surface coating, dip-dyeing and printing of various clothing fabrics, underwear, towels, curtains, etc.

1. Application in coatings and printing inks
Photochromic pigment toner is dispersed in paint and ink, insoluble in paint and ink, photochromic pigments may have different hues due to different polarities, and can be applied to oily and water-based paints and inks, suitable for various For the printing of materials, including woven materials, paper, synthetic films, mucus, glass, etc., it is advisable to use neutral or weakly acidic transparent resins (pH5-7 is the most suitable).

Applied in ink, it is suitable for all kinds of printing, including screen printing, gravure printing and letterpress printing. It is recommended to use white or light color as the printing background first, which can improve the difference of color changes. Photochromic pigments can be mixed with other dyes or pigments for even more color changes. For printing on different materials, a suitable coating or ink base should be selected. At the same time, it is also suitable for various surface coating products, including PMMA spray paint, ABS spray paint, PVC spray paint, water-based spray paint, etc.

2. Coloring application in plastic injection extrusion
Photochromic pigments are suitable for injection and extrusion molding of various plastic materials, such as PP, PE, PVC, PU, PS, ABS, TPR, EVA, nylon, acrylic, etc. The plastic melt index (MI value) is greater than 10, bending elasticity The system is less than 13000, the recommended addition amount is 0.2%~1%, generally 0.5%, the photochromic pigment should be added to the plastic material and stirred evenly during processing, and the dispersion should be paid attention to when stirring. If the dispersion is poor, an appropriate amount of dispersant can be added. Make it possible to mix it with different paints for even more color variations. After the injection molding product is formed, cooling it with supercooled water can make the color concentration of the plastic product better.
