LumaFlex™ GP 40 Phthalo Blue is a radiation-curable dispersion of 40% phthalocyanine blue (Pigment Blue 15:3) in a mixed oligomer system. This high-flow, low viscosity fluid vehicle system has been optimized for use with paper and board, with possible applications with some surface-treated or oxidized films as well. Recommended dosage of LumaFlex™ GP 40 Phthalo Blue is 45%-65% by weight in a finished ink. LumaFlex™ GP 40 series energy-curable bases feature soft easy-to-handle viscosity with excellent pigmentation levels.
Typically used to make Process Cyan inks, 45% to 65% of LumaFlex GP 40 Phthalo Blue by total formula weight is considered a normal loading for most liquid flexo & gravure ink formulas. Excellent results for coated and uncoated stock flexographic & gravure ink formulas can be obtained by blending LumaFlex GP dispersions with LumaFlex composite letdown varnish. Dense black inks made with LumaFlex GP 35 Black can also benefit from the addition of 4%-8% of LumaFlex GP 40 Phthalo Blue to increase the blue tone of the dense black ink formula.
