Radion Extender UVP is a high-tack, free flowing 100% acrylate-based all-in-one letdown vehicle for UV-cured offset inks for paper and board substrates. Radion Extender UVP is intended to be combined with energy-curable pigment dispersions such as RadionBase™ PBX as a sole letdown vehicle. Thus, as few as 2 ingredients can be utilized to formulate light-colored sheetfed and web offset inks like yellows and reds, because the proper amount of photoinitiator is already included in Radion Vehicle UVP.

For darker colors such as blue and black, extra photoinitiator should be incorporated into the mix of dispersion and Radion Extender UVP. For blue and similarly-shaded inks, use 4% extra photoinitiator. For black and similarly-shaded inks, use 6% extra photoinitiator such as Kerley's Exocure C-Liquigel photoinitiator package for low-pressure mercury vapor lamps. 

​

In most cases, only 2 to 4 ingredients are necessary to make any of the 4 process colors when Radion Extender UVP is used as the sole letdown vehicle,
