Pigment blue 36

Pigment Blue 36 (CAS 68187-11-1), also marketed as Ferro Blue-Green F 5686, Daipyroxide Blue 9421, and known generically as cobalt chrome blue-green spinel, is a high-performance inorganic pigment engineered for demanding coloration applications.

Its spinel crystal structure delivers exceptional thermal and chemical stability, making it the preferred choice where organic pigments fail under process conditions. In industrial coatings, it provides durable blue-green coloration for high-bake automotive finishes.

Coil coatings and powder coatings require resistance to elevated cure temperatures. Plastics processors use it to color engineering polymers processed at high melt temperatures, including polyamides and fluoropolymers, where most organic pigments degrade.

Ceramic and glass applications rely on its stability through firing cycles to produce consistent blue-green tones in glazes and frits. Printing inks and textile applications benefit from its lightfastness and resistance to bleed.

This is particularly useful in outdoor-exposed or solvent-heavy systems. The product is supplied as a fine dry powder, with particle size and surface treatment varying by grade to suit specific dispersion requirements.

Standard grades are available for coatings, plastics, and ceramic end uses, with technical datasheets specifying tinting strength and heat resistance thresholds. Packaging typically ranges from small technical quantities to bulk industrial supply.

The material is often distributed in fiber drums or supersacks to meet global logistics needs. This ensures the integrity of the pigment during transport and storage for various manufacturing sectors worldwide.
