CW-Y Yellow Thermochromic Pigment Powder Temperature Activated

CW-Y Temperature Activated Reversible Thermochromic Pigment Color Changing Powder YELLOW at -5~70℃

Product parameters

Product Features

1. It can change its color with temperature changes . It shows yellow at low temperature. After the temperature rises, the color disappears and becomes colorless. After cooling, it can be restored to yellow. Because it can change color repeatedly, it is called reversible. Thermochromic pigments.

2. Moltec temperature change pigment is simple to use and has a wide range of applications. It can be used in many fields such as water-based/oil-based printing inks, water-based/oil-based coatings, plastics and plastics, such as: plastic injection, plastic extrusion, ceramic mugs, textile printing and dyeing, advertising Promotional materials, children's toys, plastic soft spoons, heat-relieving stickers, heat transfer stickers, printed products, etc.

3.The reversible thermochromic pigment will change color with the change of temperature (color change temperature range: -5～70℃). When heated, the structure of the internal substance changes and the color changes. When cold, the internal substance of the color change pigment recovers. The original structure is thus restored to its original color, which is reversible repeatedly. In fact, the color change temperature of thermochromic pigments is not a temperature point, but a temperature range, that is, the temperature range included from the start of the color change to the end of the color change. Different temperature control factors can be selected by different temperature control factors. A temperature-sensitive pigment that changes color at intervals.

Application of photosensitive color changing pigment:
Plastic: suitable for injection and extrusion molding of various plastic materials, such as PE, PP, ABS, PS, PVC, PU, TPU, TPR, EVA and other plastic materials. It is recommended to add 0.2-5%.
Paint: it is suitable for all kinds of surface coating products, including PMMA, painting, ABS painting, PVC painting and water-based painting. The addition ratio is recommended to be 6% - 20%.
Printing ink: suitable for printing of various materials, such as silk screen printing, transfer printing, pad printing, etc. it is used for fabrics, paper, synthetic film, glass, ceramics, plastics and other materials. It is recommended to add 15% - 30%
Textile: it can be used for surface coating, dip dyeing and printing of various garment fabrics, underwear, towels, curtains, etc.
1. Application in coatings and printing inks
The toner of photosensitive color changing pigment is dispersed in paint and ink and insoluble in paint and ink. Photosensitive color changing pigments may have different hues due to different polarity. They can be applied to oily and waterborne coatings and inks, and are suitable for printing of various materials, including weaving materials, paper, synthetic films, mucus, glass, etc, Neutral or weak acid transparent resin should be used (pH5 ~ 7 is the most suitable). It is used in ink and suitable for various printing, including screen printing, gravure printing and relief printing. It is recommended to use white or light color as the printing background first, so as to improve the difference of color change. Photosensitive powder can be mixed with dye or pigment to match more color changes. For printing of different materials, appropriate coating or ink base should be selected Bottom. It is also applicable to various surface coating products, including PMMA painting, ABS painting, PVC painting, water-based painting, etc.
2. Application of coloring in injection extrusion of plastics
It is suitable for injection and extrusion forming of various plastic materials, such as PP, PE, PVC, PU, PS, ABS, TPR, EVA, nylon, acrylic acid, etc, Melt index of plastics (MI value) is greater than 10 and the bending elasticity is less than 13000. It is recommended that the addition amount is 0.2% ~ 1%, generally 0.5%. During processing, the photosensitive and discolored pigment should be added to the plastic material and stirred evenly. Pay attention to dispersion during mixing. If the dispersion is poor, an appropriate amount of dispersant can be added so that it can be mixed with different pigments to match more color changes. After the injection molded products are formed, they can be cooled with supercooled water However, it can make the color concentration of plastic products better.
