Carbon black (or black iron oxide) is an inorganic pigment powder widely used as a concentrated coloring agent. Because fine pigment powders can easily leak, stain, and absorb moisture, they are packaged in heavy-duty, double-sealed black plastic bags during transit and storage.
Key Properties & Functions
High Tinting Strength: Delivers a deep, rich black or dark grey color with minimal material required relative to the base mix.
UV & Weather Stability: Highly resistant to sunlight fading, weathering, and harsh environmental conditions.
Chemical Inertness: Non-reactive in alkaline mixtures, preventing color breakdown when mixed into cement, lime, or resin bases.
Primary Applications
Concrete & Masonry: Used to tint tile adhesives, grouts, mortar, paving stones, render, and stamped decorative concrete.
