ExoCure™ LED is a complete photoinitiator package designed and manufactured by Kerley Ink for use in most pigmented UV-cured inks. ExoCure™ LED is a Norrish type II photoinitiator featuring photoreactivity in the 365-405 nanometer wavelengths emitted by Light Emitting Diode (LED) lamps, ExoCure™ LED also has a built-in amine synergist to reduce oxygen inhibition. ExoCure™ LED contains Isopropyl Thioxanthones (ITX).  ExoCure ExoCure™ LED does not contain Benzophenone. Formulas using this product should be closely examined before food contact is recommended.


ExoCure™ LED is suitable for use in colors and coatings where film yellowing is not a significant consideration.


The main application for ExoCure™ LED is for UV-cure litho and flexographic inks for use with LED lamps in the 365-405 nanometer spectrum. ExoCure™ LED- is supplied as a  translucent crystalline solid with a pale yellow color. Upon storage, Exocure™ LED will exhibit crystallization which can be successfully reversed by the application of heat ( maximum 145°F/63°C) and mild agitation. Typically 7%-9% of ExoCure™ LED is used for lighter, more photo-transparent colors, and 10% to 15% of ExoCure™ LED-XL is used for darker and more photo-opaque colors. ​
