Pigment Blue 15:2 - High Tinting Strength for Paint and Coatings
Pigment Blue 15:2 sets the benchmark for intense, stable blue coloration in modern coatings, combining exceptional tinting strength with unparalleled weatherfastness. As a copper phthalocyanine derivative, this β-phase pigment delivers brilliant greenish-blue hues (CIE Lab*: L* 28±2, a* –18±1, b* –45±2) while maintaining chemical inertness across diverse resin systems. Engineered for industrial coatings, architectural paints, and specialty finishes, it achieves optimal color performance with minimal loading, reducing formulation costs without compromising durability.
