Pigment Blue 29 (C.I. 77007), commonly known as Ultramarine Blue, is an inorganic pigment composed mainly of a sodium aluminosilicate lattice containing sulfur. It produces a reddish-blue to violet-blue shade and has long been used in industrial and decorative coloration systems.
Originally derived from the natural mineral lapis lazuli, modern Pigment Blue 29 is produced synthetically to provide consistent quality and color performance. The pigment is known for its distinctive color tone and stability in many applications.
Due to its chemical composition and crystalline structure, Pigment Blue 29 is used in plastics, coatings, inks, rubber, and construction materials where stable blue coloration is required.

The performance characteristics of Pigment Blue 29 are related to its sodium aluminosilicate crystal structure.
Key properties include:
Color shade
Reddish-blue to violet-blue tone characteristic of ultramarine pigments.
Heat resistance
Generally suitable for many plastic processing conditions.
Lightfastness
Provides good resistance to light exposure in many applications.
Opacity
Usually offers moderate opacity.
Chemical behavior
May show sensitivity to strong acidic environments.
● Superior lightfastness: The dye has excellent lightfastness and can maintain bright colors even after long exposure to strong sunlight. The high lightfastness of Pigment Blue 29 ensures long-term color stability in outdoor and high-light environments.
● Wide range of applications: Whether it is plastics, coatings or inks, pb29 pigment can provide uniform and stable coloring effects. Its excellent dispersibility and compatibility make it suitable for a variety of materials and application needs, meeting diverse color requirements.
● Environmental protection and safety: Pigment Blue 29 complies with international environmental protection standards, does not contain harmful substances, and is safe and reliable. Its environmental protection characteristics not only provide excellent color performance, but also support sustainable development, providing green and safe color solutions for your plastic products, coatings and inks.
Pigment Blue 29 may present certain limitations depending on formulation conditions.
Typical limitations include:
Sensitivity to strong acidic environments
Tinting strength generally lower than phthalocyanine blue pigments
Shade may vary depending on formulation and dispersion conditions
When selecting Pigment Blue 29 for industrial applications, several technical factors are typically considered:
Desired color shade (ultramarine blue tone)
Processing conditions such as temperature and pH
Compatibility with polymer, coating, or construction material systems
Opacity and tinting strength requirements
Different commercial grades may vary in particle size distribution and application suitability.
