Photochromic Pigment Powders

Photochromic pigment changes color when exposed to sunlight or UV light, and reverts to the original color when removed from the light.
Color conversion: from colorless to colored, from one color to another color.

It can be used in making photoluminescent products, including paint, printing ink, printing paste, plastic, etc. Photochromic pigment is suitable to be printed on various kinds of material, such as fabric, paper, synthetic film, glass, ceramics, paper, metal, plastic injection and extrusion, etc. Create color changing T-shirts, caps, clothing, beads, etc.

Attention

This pigment does not react to temperature or room light, only to UV exposure. The color will change after exposure to ultraviolet light for 1 second, and the color before the change will be slowly restored after 20-60 seconds. Some colors have slightly different recovery times. The color of underneath material can't choose too deep, generally choose transparent changing effect is best. Photosensitive variable powder is harmless to human body, comply with SGS, such as the European toys EN71 certification toys and food packaging safety standards. Outdoor product is unavailable. Do not mix with strong acid and alkali products

Photochromic Pigments FAQ

Photochromic powder, also known as UV powder or photosensitive powder, uses the energy of UVA to open photosensitive molecular bonds, leading to a change from the low energy level to high energy level. That is, invisible light changes to visible light, resulting in a change in color. When ultraviolet radiation is disabled or the temperature exceeds 45℃, photosensitive molecular bonds will be closed to restore the original color. That is, the powder changes from the colorless to color status in the sunlight or ultraviolet radiation. In the absence of sunlight or ultraviolet radiation, it will return to the original color.

It absorbs ultraviolet light of appropriate wavelength to change color. In the absence of ultraviolet light of appropriate wavelength, the powder will return to the original color (from the colorless to color status). Products containing photochromic powder are mostly for color changes indoors (without ultraviolet light) and outdoors (with ultraviolet light).

Photochromic powder has the photochromic effect of typical organic systems, accompanied by reversible oxidation-reduction reaction. In the light of appropriate wavelength and intensity, the molecular structure of photochromic powder will change, and the light absorption peak (i.e. color) will change accordingly. In addition, such change is generally reversible.

Photochromic powder is suitable for the injection and extrusion of water-based inks, coatings, oil-based inks, coatings, and plastics. Photochromic powder is suitable for: injection and extrusion of oil-based inks, water-based inks, coatings, and plastics. Photochromic masterbatch is not suitable for the injection and extrusion of oil-based inks, coatings and water-based inks. It is suitable for the injection and extrusion of plastics.

Photochromic powder is usually added into cosmetics according to the prescribed proportion. It will not cause too much irritation to the skin in case of no quality problems. That is, an appropriate amount of photochromic powder is not harmful to the skin. However, excess photochromic powder may cause redness and burning sensation on the skin.

The proportion of photochromic powder in pressed powder, lipstick, eye shadow, nail polish and aerosol hair spray are 3% under normal circumstances. If cosmetics containing pearl powder is used, it is recommended to clean the skin and take moisturizing measures in time every day, to avoid harm to the skin.

The cumulative time of exposure to sunlight or ultraviolet radiation is 8h. Photochromic powder deteriorates in the sunlight. It should be kept in a cool, dry, and completely dark place. The majority of color change pigments change little in performance after 5-year storage.

Yes, photochromic powder will change in the molecular structure when it is exposed to sunlight/ultraviolet light, resulting in color effects. In the absence of sunlight/ultraviolet light, it will return to the original molecular structure, without any color.

Photochromic powder can be mixed with each other or used together with oil soluble dyes, pigments, and fluorescent dyes to produce various effects. Dyes vary in color change rates. If photochromic powder is mixed, color change will vary over time.

In case of no fatigue, the color change of photochromic powder is reversible. Photochromic powder can return to its original color in the absence of sunlight/ultraviolet light.

The proportion of photochromic powder is 6% to 20% under normal circumstances.

Coatings: surface coatings, including PMMA paint, ABS paint, PVC paint, water-based paint, etc.

Inks: The recommended proportion of photochromic powder is 15% to 30%. Photochromic powder is suitable for printing on various materials, including fabrics, paper, synthetic films, glass, etc.

Plastic injection: suitable for injection, extrusion, and molding of ABS/PE/PP/PVC/PU/EVA/silicone/rubber. Products include photochromic bracelets, yarns, shoes, etc.

Precautions for the use of photochromic powder:
  1. The most suitable pH value of a substrate is 7-9.
  2. The photosensitive 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 the resistance to photosensitive fatigue.
  3. The additives used in photochromic materials, such as antioxidants, thermal stabilizers, UV absorbers, and inhibitors, can improve the resistance to photosensitive fatigue. However, the proportions of additives are dependent on the medium used. Incorrect proportions of additives will accelerate photosensitive fatigue.

Photochromic powder is resistant to the high temperature of 220°C. It must not be used above this temperature value.

How can photochromic powder not fade on fabric?

It is often reported that fabric applied with photochromic powder will fade after washing, thus affecting the product quality. So, how to make the powder stay put? Here is a good way to do this for everyone.

What are the price differences in photosensitive pigment powders?

Photosensitive pigment powder is sold at variable prices in the market, but with similar powder. Why are some particularly expensive and others relatively low? There is also a significant difference in quality, some are good and some are bad. What are the differences specifically?
