Characteristics of chameleon powder

a) In the use of chameleon paint and printing inks, it is recommended to use a dark background to produce the best color effect on the black base.

(2) In the coating industry, it is recommended to use a one-component varnish mixed with chameleon paint in the middle layer paint of the primer, and a two-component polyurethane light with good fullness in the top coat.

Oil to cover the light.

Chameleon inks and coatings are high-tech special inks and coatings with innovative optical effects.

According to the different angles of observation, it produces three-dimensional color change effects, and does not contain heavy metals. It can be combined with other pigment dyes to induce lures.

Human color effects. At present, it has been widely used in automobiles, motorcycles, sporting goods, daily necessities, cigarette packets, and plastics.

Products and other industries.

Photochromic material Photochromic Material

First, the principle of color change:

The photochromic material undergoes a color change after being exposed to sunlight/ultraviolet light; it returns to its original color when it loses sunlight/ultraviolet light.

Second, the basic four colors: purple, red, blue, yellow. (no color change)

Third, the mutual color between the basic colors

Fourth, photochromic pigments can have many uses:

Coating: Photochromic pigment is recommended to add 10-30%, suitable for all kinds of surface coating products, including PMMA spray paint, ABS spray paint, PVC spray paint and water spray paint;

Ink: Photosensitive color-changing pigments are recommended to add 20-40%, suitable for printing of various materials, including fabrics, paper, synthetic film, glass, etc.;

Plastic products: Photosensitive color-changing pigments are recommended to be added in a ratio of 0.8-3%. It is suitable for injection molding and extrusion molding of various types of silicone and plastic materials. The products have high-density photosensitive PE, ABSPS masterbatch and photosensitive PMMA masterbatch products.

Five, note:

1. The substrate is selected to be the most suitable material with a pH of 7~9.

2. The maximum temperature resistance of the photosensitive color-changing material is 230 ° C, and can not be operated above 230 °.

3. Photo-fatigue of photochromic materials is caused by excessive exposure to ultraviolet light (UV light) and high humidity. It is recommended to add light absorbers and antioxidants to increase anti-light fatigue.

4. Additives used in photochromic materials (antioxidants, thermal stabilizers, ultraviolet light (UV light) absorbers and inhibitors can improve light fatigue resistance, but the ratio of additives is based on the medium used, the wrong ratio Will accelerate the occurrence of light fatigue.

5, photosensitive color-changing materials do not contain harmful substances harmful to the human body, in line with safety toys and food packaging specifications.

 Angle color changing powder (optical color change)

The angle color powder (ink) graphic color changes with the change of the angle of view. When the angle of view changes by 60 degrees, two distinct colors are produced. The first color is seen when it is totally reflected, that is, the color seen when the angle of view is 90 degrees, when twisting 60 degrees to 30 degrees of view. The first color is cancelled and the second color is strengthened. This is a high-tech security anti-counterfeiting ink that can be printed using traditional engraving gravure. It does not require complicated or additional inspection equipment to distinguish between authenticity and is suitable for banknotes, tickets, packaging, etc. Refractive color inks are very concealed and difficult to decipher. They are developed for the development of color inks, such as laser scanning color separation machines and color copiers.
