RadionBase™ PBX Carbazole Violet
Packaging Options:

RadionBase PBX Carbazole Violet is a radiation-curable dispersion of 31% Carbazole Violet (Pigment Violet 23) in a mixed oligomer system. Violet 23 is recognized as the "gold standard" for lighfastness and color retention among violet-shade pigments. This vehicle system has been optimized for use in paper and board, with possible applications in surface-treated or oxidized films as well. Recommended dosage of RadionBase PBX Carbazole Violet is 36%-50% by weight in a finished ink. RadionBase PBX series energy-curable bases feature soft easy-to-handle viscosity with excellent pigmentation levels.

Typically used to make Violet or Coatable Reflex Blue inks or used as a toner in black inks to improve their blueness of shade, 36% to 50% of RadionBase PBX Carbazole Violet by total formula weight is considered a normal loading for most paste ink formulas. Excellent results for coated and uncoated stock litho & web offset ink formulas can be obtained by blending RadionBase PBX dispersions with Radion Vehicle UVP composite letdown varnish. As a toner, used 3%-12% of RadionBase PBX Carbazole Violet to tone black inks. RadionBase PBX series bases can be used for mercury UV, HUV, and LED UV formulas. ​

 

Blend 2 parts RadionBase Carbazole Violet to 1 part RadionBase PBX Phthalo Blue to make an excellent lightfast and "bulletproof" Reflex Blue Ink.
