Liquid packaging inks formulated with non-abrasive micronized ultramarine blue protect gravure and anilox cylinders while delivering deep color saturation.
In high-speed flexographic and gravure printing, abrasive inorganic pigments cause premature cylinder wear. RS Pigments refines its particles to sub-45 micron fineness (<0.1% residue on 325 mesh).
This delivers gentle processing on expensive engraving rolls while maintaining total insolubility in packaging solvents, alcohols, and esters.
Key Technical Takeaways
- Ultramarine Blue is chemically non-nucleating, eliminating shrinkage and warping in HDPE and PP injection moldings.
- Thermal stability up to 350°C in specialized heat-resistant grades and NANOX compounding platforms.
- Total resistance to alkaline environments (5/5 rating), ideal for masonry coatings, concrete, and laundry powders.
