It’s an ultra-fine powder with a thickness of about 2-3um, which can give your finished product an amazing linear rainbow effect. As a pigment decoration product, it has been widely used in cosmetics, printing and coating, automotive paints, and many other fields.
The holographic pigment powder is also known as optical diffraction powders, or optical structural color powders, because the color effects we see are produced by micro-nano optical technology, showing different colors and 3D effects through micro-nano structures.
The beautiful optical color perfectly combined with the magnetic 3D effect makes your products elegant and attractive.
Apply it to your nails to create a bling-bling, dazzling rainbow effect. And they can work well with different base colors.
Applicable to the coating process and spraying industry. And finally used to make decoration parts and vehicle wrap films.
Used in the printing industry, like silkscreen printing and gravure printing, for producing package materials and cards.
Compared with traditional metallic pigments, the holographic glitter pigment has better dispersion in resin, providing a brighter and more reflective surface. And none of them have a substrate and are very thin. When customers use it, the consumption will be small. The grain size varies from 20um to 70um, of which the magnetic particle size is 35um, 50um, and 75um.

Optical powders have been widely used in coating, spraying, silk screen printing, gravure printing, manicure, and other processes. Create distinct designs that will make your products stand out from the crowd.
Our company is a professional manufacturer of optical structural color powder, The powder has great optical features, which create an amazing visual effect on your products. An elegant, attractive look that enhances brand uniqueness and makes your products unique.
In addition, we also supply holographic magnet powder, great magnetic features that add an obvious running pillar of light and a cat-eye effect. Besides, magnets can do the special pattern.
For ink or resin with holographic pigment, compared with ordinary pure ink, the mesh diameter and depth are a little larger, and the mesh diameter size should be larger than the powder size. A laser engraving type should be selected for the anilox roller, and the effect of hexagonal and U-shaped mesh will be better. Different mesh diameters, mesh depths, mesh angles, mesh shapes, and other plate-making factors affect the final effect.

| Size | Mesh number |
| 75 um | 200 |
| 50 um | 300 |
| 35 um | 400 |
| 25 um | 500 |
| 15～20 um | 700 |
The holographic powder is suitable for coating, spraying, silk screen printing, gravure printing, and other processes. The addition proportion is 0.3 ~ 10%. The proportion can be determined according to the required effect. The addition proportion is small, showing a flashing effect. When the addition amount is large, the loose powder is dense, and there will be an aperture halo effect. The strength of the effect is also positively related to the coating amount. (Note: powder is not suitable for offset printing at present)
Dissolution sequence: optical diffraction powder infiltration → transfer in resin ink.
When used in the organic solvent system, the powder can be soaked with the organic solvent (such as ester, ketone, etc.) fused with the system. The soaking time shall not be less than 2 hours, and it shall be fully stirred to improve the dispersion. The wetted optical structural color powder is evenly added into the resin ink in proportion, and suitable dispersant or coupling agent is allowed to be added. It is recommended to use “propylene glycol or propylene glycol methyl ether” as a wetting agent, and its slurry is effective after being sealed and stored at room temperature for 6 months.
When used in an aqueous system, it is recommended to infiltrate the powder with purified water and stir it fully, so that the powder can be more evenly dispersed, and the soaking time shall not be less than 2 hours. The wetted powder is added to the resin ink in proportion, allowing the addition of appropriate dispersant or coupling agent.
In actual use, if ethanol is needed as the diluent, it is recommended to use it when the concentration is less than 10%, and do not store the solution containing ethanol for a long time.
When used in an aqueous resin system, avoid wetting the powder with solvents such as ethanol, organic ester, ketone, and toluene, and do not use tap water as the wetting agent.
The PH value of the solution containing optical diffraction powder is recommended to be about 7 to avoid acid-base erosion.
