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. It delivers a bright, clean blue hue with strong heat stability and alkali resistance.

This pigment is a preferred colorant across demanding industrial and decorative applications. In architectural and industrial coatings, it provides durable blue tones in exterior paints, primers, and powder coatings where UV stability is critical.

Plastics processors incorporate it into polyolefins, PVC, and engineering polymers to achieve consistent blue coloration through high-temperature compounding. Printing inks and packaging applications rely on its clean mass tone and tinting strength.

The material is suitable for offset, flexographic, and gravure formulations. In construction materials such as fiber cement, concrete, and caulks, it delivers stable coloration without affecting cure chemistry or substrate adhesion.

Pigment Blue 29 is supplied as a dry powder in standard pigmentary grades. Specifications vary by particle size distribution and tinting strength, with grades available for coatings, plastics, and cosmetic applications.

Technical and cosmetic-grade versions are the most commonly stocked forms across the supply chain. These grades ensure compatibility with various binders and resins while maintaining high color consistency and dispersion properties.
