PB28 Cobalt Blue is a high-performance inorganic blue pigment known for its thermal and chemical stability. However, no pigment is universally suitable for all applications. This article explains when PB28 may not be the optimal choice and highlights key limitations, trade-offs, and alternative considerations for pigment selection.

Detail

In high-temperature plastics, industrial coatings, and ceramic ink applications, blue pigments often fail due to thermal, chemical, or dispersion-related limitations. This article analyzes common failure modes of organic blue pigments and explains why inorganic PB28 Cobalt Blue provides superior stability and long-term performance in demanding processing environments.

Detail

PB28 Cobalt Blue can be manufactured via different synthesis routes, primarily solid-state and liquid-phase processes. These process choices significantly influence particle size distribution, agglomeration behavior, color consistency, and dispersion performance in plastics, coatings, and ceramic ink applications. This article compares the two routes and explains their implications for high-end and fine-dispersion systems.

Detail

PB28 Cobalt Blue Pigment is a high-performance inorganic blue pigment based on cobalt aluminate spinel structure. It is widely used in high-temperature plastics, industrial coatings, ceramics, glass, and ceramic ink applications requiring thermal and chemical stability.
