SOLVENT-SOLUBLE FLUORESCENT TONERS FOR PRINTING INKS
Chartreuse, Green, Orange-Yellow, Orange, Orange-Red, Red, Cerise, Pink, Magenta, Blue
RECOMMENDED APPLICATIONS
Solvent-based flexographic and gravure printing inks, and UV-cure inks. Can be applied on gift wraps, label stocks, tissue coating, corrugated containers, flexible packaging papers, plastics, glass, metal, wood, films, foils, and other specialty coatings. For indoor applications.
SUMMARY OF PROPERTIES
Form: dry granular powder, thermoplastic,
Solubility:
Excellent in propyl acetate, isopropyl acetate, ethyl acetate, 2-Nitropropane, Diethylene glycol, Dipropylene glycol;
Good in Monochlorobenzene, Orthodichlorobenzene;
Good in Ethylene glycol monoethyl ether, Ethanol, Isopropanol, Propylene glycol when used as cosolvents.
Compatibility: Compatible with most flexographic ink binders, including nitrocellulose, ethyl cellulose, cellulose acetate butyrate, other alcohol-soluble butyrate, acrylics, ketone resins, and maleic resins. Also compatible with low percentage (around 2%) waxes and/or polyethylene dispersion additives. More compatible modifiers have to be applied to improve the limited compatibility with Polyamide resins.
STORAGE AND SHELF LIFE: When stored in a sealed container, away from heat, humidity, and direct sunlight, UNE toners have an indefinite shelf life.

1.Ethyl acetate may be replaced with less volatile isopropyl acetate or normal propyl acetate (active retarder solvents) to improve leveling properties or to slow the drying rate
2.Viscosity is measured by Brookfield, No. 1 spindle
3. Use denatured ethyl alcohol
Flexographic inks prepared with UNE toners can be formulated with better cellophane tape resistant adhesion, crinkle resistance, block resistance and abrasion resistance. Reference formulations are available upon request.
