Pigment blue 29

Pigment Blue 29 (CAS 57455-37-5), commercially known as Ultramarine Blue, is a synthetic inorganic pigment derived from calcined aluminosilicate minerals.

Where is Pigment blue 29 used?

• Architectural and industrial coatings: durable blue tones in exterior paints, primers, and powder coatings where UV stability is critical
• Plastics: blue coloration of polyolefins, PVC, and engineering polymers through high-temperature compounding
• Printing inks and packaging: clean mass tone and tinting strength for offset, flexographic, and gravure formulations
• Construction materials: stable coloration of fiber cement, concrete, and caulks without affecting cure chemistry or substrate adhesion
• It delivers a bright, clean blue hue with strong heat stability and alkali resistance.

Commercial specifications

• Specifications vary by particle size distribution and tinting strength
• Grades available for coatings, plastics, and cosmetic applications
