Photochromic Material

Photochromic Material is a photochromic powder material manufactured by wrapping photochromic dyes in microcapsules through special processes, which can absorb the energy of sunlight (ultraviolet) after being irradiated by sunlight (ultraviolet), resulting in changes in molecular structure, resulting in changes in absorption wavelengths, resulting in color changes; When sunlight (ultraviolet) energy is lost, it returns to its original molecular structure and restores its original color. Characteristic:

1. The average particle size of photovariable powder is 3±1μm, which is a photovariable material processed and prepared by microencapsulation technology, which is simple to use and widely applicable, and can be used in inks, coatings, injection molding and other fields.

2. The product is safe and reliable, non-irritating to the skin, and does not contain substances harmful to the human body.

Notes:

1. If there is a high-temperature process, it is recommended that the processing temperature is not higher than 220 degrees.

2. Adding heat stabilizers, reducing processing temperatures, or shortening high-temperature processing time can help improve the color-changing properties of the final product

3. The substrate selection is the most suitable material with a PH value of 5-7.

4. It should be sealed and stored in a closed and dry place, avoiding direct sunlight.

5. Photochromic powder does not contain harmful substances to the human body and meets the standards of safe toy and food packaging specifications.

6. It is recommended that customers try it before use, if they need further technical support, please contact us.
