Application columns are normalized from TRESAI technical data sheet application fields: Ink covers offset, solvent, water-based, NC and UV printing inks; Coating covers industrial, automotive, architectural and powder coatings; Plastic covers masterbatch and engineered resins; Textile covers textile printing and dyeing. A dash means the grade is not listed for that field on its technical data sheet.
Chemical Classes in This Family
This blue selection covers 2 chemical classes: Phthalocyanine (7); Indanthrone (Anthraquinone) (1). Class chemistry is the fastest predictor of solvent fastness and outdoor durability within a color family.
