Common color-changing pigments, which one is right for you?

Color-changing pigments are pigments that change color, in the previous Xiaobian has introduced us to the basic information of common color-changing pigments (light-changing powder and temperature-changing powder), maybe some people are eager to try to start buying this color-changing pigment, so that their products have more characteristics. So where do we start when buying color-changing pigments? Although there are not many types of color-changing pigments, there are many different options for different product uses.

It should be noted that the common basic types of color-changing pigments are photochromic pigments, temperature-sensitive color-changing pigments, etc., which have their own advantages and uses, and can be selected according to their own conditions.

1. Photochromic pigments

Photochromic powder is also known as photochromic powder, photochromic pigment, photochromic powder, etc. The principle of photochromic powder is that the compound with photovariable function will undergo reversible changes in its molecular structure under the excitation of a certain wavelength and intensity of light source, which is intuitively manifested as a change in color, and after the excitation is suspended, the compound will recover to the initial state, and the intuitive performance is that the color decays to the initial condition.

The scale of use is mainly in clothing fabric printing, ceramic mugs, printing, printing and dyeing coatings, plastic injection, plastic extrusion, plastic injection molding, various conceptual gift production, advertising materials, children's toys, art design, etc.

2. Temperature-sensitive color-changing pigments

Thermochromic powder is a microencapsulated reversible thermochromic substance, which is called reversible thermochromic pigment (commonly known as: thermochromic powder, thermochromic pigmentor thermosensitive powder), its color-changing principle is mainly composed of three parts: color-changing dye, chromogenic agent and solvent. At high temperatures, the color-changing dyes and chromogens dissolve in the solvent and the system appears white. When the temperature drops, the solvent gradually condenses, the chromic dye and the chromogen are close to each other, and under the action of the chromogen, the structure of the chromogenic dye changes, so that the system flashes color. By adjusting the condensation temperature of the solvent, it is possible to prepare temperature-varying products that change color at different temperatures.

The products are widely used in textile and garment fabrics, children's educational toys, anti-counterfeiting identification, conceptual gifts (such as cups, card coupons), art design, warning function, memory function, antibacterial and antivirus, logo restoration, education and medical care, beauty and skin care, food packaging, ceramic supplies, smart home, coatings and many other industries.

The color-changing pigments listed above are the two most common, and each has its own characteristics depending on its characteristics. For example, photochromic raw materials mainly rely on the energy of the light source to produce color changes, while thermochromic pigments are based on different temperatures to produce color changes, these different characteristics we need to carefully consider when purchasing color-changing pigments, combined with their own economic conditions, product characteristics, etc., to make a rational evalsuation, and then choose a relatively suitable color-changing pigment products.
