Photochromic Pigment

Photochromic pigment and powder changes colour in the sun and under certain levels of UV exposure. The product turns from an almost colourless powder into vibrant colours if it is exposed to the ultraviolet rays. Once the direct UV source is removed from the product, it reverses back to colourless again. 

This product can be used for a number of applications including coatings, printing and plastic injection moulding. Due to the flexibility of photochromic powder it can be applied to a range of substrates such as ceramics, glass, wood, paper, board, metals, plastics and fabric.

These colour changing powders can be used for silkscreen, gravure and flex printing. They can also used in line with PU, PE, PVC, PS and PP for plastic injection. Heat can be applied for less than 10 minutes if the temperatures do not exceed 230 degrees Celsius. Please avoid prolonged exposure of temperature if it exceeds 75 degrees Celsius. 

Photochromic pigment contains a microencapsulated photochromic dye. The photochromic dye is encapsulated with a synthetic resin to provide extra stability and protection from additional additives and chemicals used in the manufacture of coatings and plastics.

SFXC photochromic powder is odourless and contains less than 1% moisture. The particle size is 2-5um and has a shelf life of around 12 months. The powder is easy to disperse, has a quick response time and offers a strong colour density once activated by ultraviolet rays. 

This product has a light fastness grade of 1. Continued exposure of UV can damage the photochromic dyes and alter or stop the colour changing effect.

SFXC photochromic powder/pigment is available in 5 colours which include blue, magenta, violet, yellow and orange.

Before using these powders, please run prior texting to ensure this product is suitable to use in your chosen application.
