• Varying degree of color change PERMANENCY from completely IRREVERSIBLE to LONG PERIOD FADEOUT (weeks/days) to standard FAST-FORMING/FAST-REVERSING photochromics

• COLOR CHANGE response to various UV and visible light sources (including office and daylight fluorescent lamps), as well as sun exposure

• Product customization for specific applications

• Joint Research & Development Projects are possible and encouraged. Confidentiality ensured
