Cobalt Violet (PV514A), developed by Kela Materials, is an inorganic purple pigment produced by high-temperature calcination of cobalt phosphate. It delivers a pure, brilliant violet shade with medium depth and excellent color clarity.

This pigment shows outstanding stability, non-migration, and excellent compatibility with both organic and inorganic pigment systems, enabling fine-tuning of color tone and tinting strength across coatings, plastics, and artistic applications.

PV514A provides excellent heat resistance, lightfastness, and outdoor weather durability. However, as with most cobalt phosphate pigments, its acid and alkali resistance is relatively low, making it best suited for neutral or slightly acidic systems.

FAQ

What is Kela Cobalt Violet PV514A?
Kela Cobalt Violet PV514A is a high-purity inorganic purple pigment produced by high-temperature calcination of cobalt phosphate, offering a clean, brilliant violet shade with excellent stability.

What are the main advantages of PV514A?
It provides excellent heat resistance, lightfastness, and outdoor weather durability, with a non-migrating inorganic structure and good compatibility with most resin and polymer systems.

Where is PV514A typically used?
PV514A is used in high-performance coatings, plastics, masterbatch, ceramics, artistic paints, and other applications that require long-term color stability and a pure violet tone.

Can PV514A be blended with other pigments?
Yes. It can be combined with both organic and inorganic pigments to fine-tune color tone, depth, and tinting strength in coatings and plastic systems.

Does PV514A have any limitations?
Like most cobalt phosphate pigments, its resistance to strong acids and strong alkalis is relatively low, so it is best used in neutral or slightly acidic systems.
