Photochromic dye

Photochromic dye does not react to sunlight/UV and need to be dissolved in medium(solvent, resin, or polymer)to function

 Photochromic dye does not react to sunlight/UV and need to be dissolved in medium(solvent, resin, or polymer)to function, Polarity of the medium is directly related to the color.

A. properties

the photochromic dye is an organic dye completely pervious to light, suitable for plastic injection and solvent based ink/paint.

B. Recommended concentrations

For solvent based ink/paint        1.0%-10% w/w

(For best result, about 2% concentration is required for 20um film thickness)

For plastic injection/extrusion      0.1-1% w/w

(For best results, about 0.01% concentration is required for 0.2cm plastic thickness)

C. General Recommendations

Overexposure to sunlight, acids, free radicals and humidity may cause poor fastness, which could be improved by adding uv absorbents and anti-oxidants, specific formulations of uv absorbents or anti-oxidants should be used depending on the media, improper formulations speed destroying color fastness and end up destroying the color changing properties.

The photochromic dye can not be injection molded at temperatures over 250°C due to its low decomposition temperature.

The solvent compatibilities of photochromic dye are different, there are standard formulations available for ink/paint applications please contact sales representative for more information.
