Enamel Colors Black Chrome Iron Brown Hematite

 

PBr 29, also known as chrome iron brown or iron chromite brown/black, is a mixed metal oxide pigment with a hematite-type structure. It offers strong performance in enamel applications.
 

FULLN CHEMICAL Enamel Colors Black Chrome Iron Brown Hematite FU-E683 is a black inorganic pigment obtained from raw materials such as ferro red and chrome green. During the process of high temperature calcination, ferro red (Fe2+), (Fe3+) and chrome green (Cr3+) ions react with each other and spread evenly, form a substance with spinel crystal structure.

 

 

 

 

 

 

 

 

 

Key Advantages in Vitreous Enamel
Excellent Thermal Stability
Withstands standard enamel firing temperatures (typically 750–850°C) without significant color change or decomposition.

High Chemical & Weather Resistance
Highly resistant to acids, alkalis, UV light, and atmospheric exposure, ensuring long-term color retention in both indoor and outdoor applications.

Good Coloring Strength & Opacity
Provides a deep, rich brown to brown-black color with strong covering power, allowing for uniform, opaque enamel coatings even in thin layers.

Good Compatibility with Enamel Frits
Integrates well with various enamel frits, promotes good melt behavior, and contributes to a smooth, glossy finished surface with strong adhesion.

Cost-Effective Stability
Generally more economical than cobalt-based black/brown pigments while still providing high temperature and chemical resistance suitable for many enamel applications.

 

 

 

 

 

 

 

Application:

Architectural panels & cladding

Cookware & kitchen appliances

Sanitaryware (sinks, bathtubs)

Industrial signage & machinery panels

BBQ grills & heat-resistant coatings
 

Contains chromium, but in a stable oxide form with low solubility when properly fired, typically meeting relevant regulatory standards for cookware and construction.

Color can range from dark brown to almost black depending on particle size and exact composition.
