RadionBase™ PBX Phthalo Blue
RadionBase PBX Phthalo Blue is a radiation-curable dispersion of 35% phthalocyanine blue (Pigment Blue 15:3) in a mixed oligomer system. This vehicle system has been optimized for use in paper and board, with possible applications with some surface-treated or oxidized films as well. Recommended dosage of RadionBase PBX Phthalo Blue is 40%-55% 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 Process Blue (Cyan) inks, 35% to 55% of RadionBase PBX Phthalo Blue 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. RadionBase PBX series bases can be used for mercury UV, HUV, and LED UV formulas.
