Radglo® STX-09

Solid solution of fluorescent dyes in polyester resins. It represents a unique fluorescent ink system which, although delivered in dry form, is totally water-soluble. With the addition of a small amount of ammonia and alcohol, but without other binder additives, a complete water ink system for flexographic and/or gravure ink can be formulated. Water-based inks made from STX exhibit excellent film forming properties, color strength and high gloss. Exhibits excellent transparency making it the system of choice for printing on foil and film. The lightfastness of STX toners is superior to most solvent-based fluorescent flexographic and gravure inks. The lightfastness may be improved by including UV– absorber(s) in the formulation and/or by making use of clear overcoats containing UV-absorber. Used in water based flexographic & water based gravure inks.
