Phthalocyanine Blue B Pigment Blue 15 for Paints Inks and Plastics

Not directly. The pigment itself doesn't cause foaming, but the surface treatment on some grades or the air introduced during high-speed mixing can trap bubbles. Check your formulation's defoamer or antifoam agent - you might need to increase the dosage or switch to a more effective one. Also, adjusting the mixing speed or adding pigment slowly can reduce air entrainment.

Settling can happen if the pigment is stored in a humid environment or if the packaging gets damaged and moisture gets in. The powder can cake or form hard lumps over time. What to do: Keep bags in a dry, well-ventilated area off the floor (use pallets). Make sure packaging is intact before storing. If lumps do form, they can usually be broken up by sieving or re-grinding before use-but it's extra work, so prevention is better.
