Introduction to Ouke Chameleon Pearlescent Pigment

The excellent chemical and high temperature resistance of pearlescent pigments offers its wide application in coatings, inks, plastics and many other fields. They provide a new color system and color quality for these products. Pearlescent pigments have low levels of heavy metals and meet relevant safety technical standards, making them suitable for food packaging and children's toys. Both acid and alkali do not erode the pearlescent pigment at room temperature. Pearlescent pigments can not burn, are not self-igniting, non-conductive, and can withstand high temperatures of 600 and 800 °C. Pearlescent pigments can also be used in reactive coatings for radiation curing systems (electron beam curing, photocuring). The special surface chemical structure of pearlescent pigments makes them excellent in hydrophilicity, so it can be applied to water-based coatings, but it has poor lipophilicity. Therefore, when used in organic systems, there is a problem of poor dispersibility, and surface treatment of pearlescent pigments is required. It also makes it well suited for use in organic systems.

Creative Chameleon Color Concept:
For the manufacturer, it is necessary to invent a formula that imparts both the color of the object and the color effects that can only be found in nature under normal conditions (such as pearlescent luster, iridescent effect, deep gloss, and color drop). ), this is definitely a very difficult and challenging job. In the twentieth century, synthetic pigments have been able to simulate some of the amazing visual effects in nature. Typical examples include the use of titanium dioxide or other metal oxides to coat the translucent mica to achieve a pearly luster effect. With the birth of high-color chameleon pigments, a new color concept began to enter the paint industry. Now, even the most spectacular color effects in nature can achieve a deep, shiny, bright, and significant color change. A chameleon pigment consists of a network of organic polymers comprising a crystalline phase of a so-called cholesterol liquid derived from sugars.
Optical effect:
A typical pigment or dye absorbs light in a particular wavelength range of light and reflects the rest. Chameleon pigments are transparent platelets with a helical structure that do not absorb light but only reflect and transmit light, thus creating a color effect through optical interference effects, just like soap bubbles. In the spiral structure, cigar-shaped liquid crystal molecules are arranged in parallel rows. Each layer has a slightly different molecular orientation. We define the distance between two layers with the same molecular orientation as the pitch, which determines the color of the lamella. A typical chameleon pigment platelet has approximately 10 superimposed pitches, each reflecting light. In the incident light, the light whose wavelength matches the pitch of the particle will be reflected, and the rest will be transmitted to the surface of the object. Due to the transparency of the pigment, the color of the object itself plays a very important role in the application of the chameleon pigment. When a chameleon pigment is used on a dark color, especially on a black surface, a unique color effect that changes color depending on the viewing angle can be obtained. Conversely, on a white or off-white background, only a very subtle flickering effect of color change is produced because the background reflects most of the incident light.
Unique and true:
Chameleon pigments add fresh power and personality to your products. Whether your product is a car, sports equipment, communication tools, toys, leather, textiles, cosmetics, or other items, the surface layer of Chameleon pigments will take them to a premium grade of their own. The emergence of chameleon pigments heralds the arrival of a post-metal era. Chameleon pigments are leading a new era in the field of coloring. It will revolutionize the formulation of your paint, paint, plastics and cosmetics industries. Your customers will also focus on your products with an incredible look and give you a heartfelt admiration!
Application Guide:
Chameleon pigments have a wide range of applications due to their ease of processing and special color effects. In the formulation of the transparent system, chameleon pigments can achieve the best color effect. For applications with a deep gloss effect, the surface of the product should be covered with a clear coating. Chameleon pigments are used in paints, coatings, printing inks and plastics. An opaque or light scattering component will reduce the color change until the desired brightness effect. By mixing with other pigments (such as metal, pearlescent pigments), you can get a very attractive effect. In clear plastics, the desired hiding power is obtained by adding a small amount of carbon black (about 0.01%). The chameleon pigment particles should be arranged in parallel during the application of the paint. This will give you the best results. For outdoor applications, it is recommended to add a UV absorber. The following characteristics of chameleon pigments:
Compatibility with all types of adhesives in powder, aqueous, solvent-based formulations
Lower density, eliminating the problem of sedimentation
Transparency, can be used on the surface of colored objects.
Expand product range:
The bright scenery brought by the chameleon pigments from time to time gives the object vitality. You can change the hue of the color by:
1. Change the color of the bottom layer,
2. Mix two types of chameleon pigments,
3. Chameleon pigment is mixed with other colorants.
Transparent paints, paints and color pastes using chameleon pigments create a new color feel and expand your product range. By combining your products with different color substrates, your customers can get a variety of color changes with just a few of your products.
Non-toxic and tasteless pigments:
The safety of chameleon pigments lies in:
Free of heavy metals and other toxic substances
Can be harmonized with the surrounding environment,
The environmental authority is defined as a non-toxic and harmless colorant.
