Pigment selection by application and industry
Pigment Selection for Printing Inks: Every Formulator’s FAQ Pigments are the most expensive component in printing ink — typically 15-30% of total formulation cost — and they determine everything downstream: color, printability, durability, and regulatory compliance. Yet pigment selection is often treated as a procurement decision rather than a technical one. This FAQ addresses the … Read more
TL;DR 100 grams is not a qualification sample. It’s a first-look drawdown. If you’re running dispersion, viscosity, colorimetry, and QUV aging, you need 200-300 g minimum, and that assumes nothing fails. Run tests in the right order—dispersion first, then hue, then viscosity, then aging—so you stop on the first failure and don’t burn material you … Read more
