Exocure™ LED-W is a multi-purpose photoinitator for LED UV-cured white paste inks, coatings & clear vehicles. ExoCure LED-W is a complete photoinitiator package designed and manufactured by Kerley Ink for use in most white LED UV-cured inks, and in clear LED UV-cured coatings. ExoCure LED-W is a Norrish type I photoinitiator package featuring photoreactivity in the wavelengths emitted by low pressure mercury lamps.

Exocure™ LED-W is recommended for use in colors and coatings where film yellowing is a significant consideration. ExoCure™ LED-Walso has a small percentage of an amine synergist to reduce oxygen inhibition. ExoCure LED-W is supplied as a light color, free-flowing fluid. ExoCure LED-W does not contain Benzophenone. Upon storage, Exocure™ LED-W may exhibit some crystallization which can be successfully reversed by the application of heat ( maximum 145°F/63°C) and mild agitation.

Typically 9%-11% of ExoCure LED-W also has a built-in amine synergist to reduce oxygen inhibition. is used for lighter, more photo-transparent colors, and 10% to 16% of ExoCure LED-W is used for more photo-opaque colors. Exocure LED-W should be used at levels of 12%-15% for fast-cure coatings and OPV's.
