Excellent High-Temperature Stability
Withstands enamel firing temperatures (typically 750–850°C) without color shift, fading, or bubbling, ensuring consistent deep black coloration.

Strong Coloring Power
Provides a dense, jet-black color with high opacity and tinting strength, allowing for thin, uniform enamel coatings.

Superior Chemical & Weather Resistance
Resists acids, alkalis, and UV exposure, making it ideal for outdoor architectural enamel panels, signage, cookware, and sanitaryware.

Excellent Adhesion & Gloss Compatibility
Compatible with enamel frits, promoting smooth surface finishes, good gloss retention, and strong substrate adhesion after firing.

Thermal Expansion Matching
Its thermal expansion behavior can be adjusted to match steel, cast iron, or glass substrates, minimizing cracking or peeling.
 

 

 

 

Typical Enamel Applications
Architectural facade panels
Cookware (stovetops, oven interiors)
Sanitaryware (bathtubs, sinks)
Industrial signage & exterior cladding
High-temperature appliance coatings

Important Notes

Contains cobalt and chromium, but the spinel structure ensures low metal ion release, generally meeting food-contact and sanitary standards when properly formulated.

More expensive than iron-based blacks, but valued for its performance in premium or demanding environments.
