Product Description:
Ranbar WS4010 is a colorless-to-green reversible Thermochromic pigment made by microcapsule coating technology. Its appearance is in the form of particles with an average particle size of 2-5 microns. Its interior is Thermochromic powder. Thermochromic powder is a pigment that can cause chemical structure changes caused by heat, thus causing color changes. It is extremely sensitive to the external environment. The microcapsule coating layer strengthens the stability and chemical resistance durability of the Thermochromic powder, It also enhances the applicability of the product. When used in cutting machines such as mixers or high-speed dispersers, the outer wall layer of the pigment capsule may be damaged, affecting its color changing function. During the processing, it is necessary to pay attention to avoiding damage to this layer of coating.

Thermochromic pigment application:
1. Plastic/plastic: It can be used for injection and extrusion molding of transparent or translucent plastics such as polyethylene, polypropylene, polystyrene, soft polyvinyl chloride, AS, and ABS.
2. Coating: Suitable for surface coating of all kinds of plastic products, including ABS, PE, PP, PS, PVC, EVA, and other plastic materials, etc.
3. Ink: Suitable for all kinds of printing, including screen, gravure, and letterpress printing, can be printed on various materials, including textiles, paper, synthetic film, glass, ceramics, and wood, etc.
There are many kinds of thermochromic pigments, and the temperature range of color change can be adjusted. Different series of thermochromic pigments can be matched and combined with each other so that we can get more colorful colors, and thus create various colors and gorgeous products that change colors under different temperatures.
By matching the basic colors of thermochromic pigments with each other in a certain ratio, we can obtain the color change effect from transition color to colorless, as follows:
By matching the thermochromic pigments and common pigments with each other, we can get the effect of color change between different colors, as follows:
Notes on thermochromic pigments:
The reversible thermochromic pigment is an unstable system, so its light resistance, heat resistance, and solvent resistance are not as good as ordinary pigments, so it should be noted in use.
Light resistance: The light resistance of thermochromic powder is poor, when exposed to strong sunlight, the color-changing function may be reduced rapidly, avoiding strong sunlight and ultraviolet light is good for prolonging the service life of color-changing pigment.
Temperature resistance: Thermochromic color-changing organic matter may decompose above 80 degrees, so avoid long-time operation under high temperatures above 75 degrees.
Solvent resistance: Thermochromic pigments are sensitive to lipid solvents containing few carbon atoms, and have good solvent resistance in lipid structures containing more carbon atoms.
Storage: Ranbar thermochromic pigments should be stored in cool, dry, and completely light-proof conditions.
