LumaFlex™ GP 70 Opaque White

Packaging Options:

LumaFlex GP 70 Opaque White is a radiation-curable dispersion of 70% Titanium Dioxide (Pigment White 6) 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 70 Opaque White is 45%-60% by weight in a finished ink. LumaFlex GP series energy-curable bases feature soft easy-to-handle viscosity with excellent pigmentation levels.

Typically used to make Opaque White base layer inks, 40% to 60% of LumaFlex GP 70 Opaque White 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.
