Carbon Black (Pigment)
Carbon black (pigment black) is a finely dispersed amorphous carbon obtained through the controlled incomplete combustion or thermal decomposition of hydrocarbons. It presents as a very light powder or microgranules of a deep black color. It is widely used in industry as the most popular and intense black pigment. It provides materials with a deep, rich black color, unsurpassed hiding power, and significantly improves their physical and mechanical properties as well as UV resistance.
Applications
Paints and Coatings Industry: Used in the production of enamels, primers, automotive paints, as well as printing and typographic inks. It allows for coatings with a deep black color, perfect smoothness, and high hiding power.
Polymers and Plastics Production: Applied for the mass coloration of cable sheathing, pipes, films, PVC products, and various compounds. It serves as a powerful UV stabilizer, preventing photoaging and the degradation of polymers under sunlight.
Building Materials and Dry Mixes: Serves to pigment concrete, cement mortars, joint grouts, paving slabs, silicate bricks, and self-leveling floors. It provides a long-lasting color that does not wash out with precipitation.
Rubber and Tire Industry: Used not only as a pigment but also as a crucial reinforcing filler (reinforcing agent). It significantly increases the strength, wear resistance, and overall durability of rubber compounds.
Key Advantages
High Tinting Strength and Intensity: Due to the ultrafine size of its nanoparticles, it possesses maximum coloring power. This ensures a rich color and economical consumption even at minimal addition rates.
Excellent Compatibility and Versatility: Easily dispersed (especially in granulated form or when using dispersants) in most aqueous and organic media, resins, and polymer melts, without deteriorating the rheological properties of the base material.
Absolute Light and Weather Resistance: It is one of the most stable inorganic pigments in the world. It does not fade under direct sunlight (UV radiation) and reliably protects the colored material from environmental degradation.
Chemical and Thermal Inertness: The pigment is absolutely resistant to aggressive acids, alkalis, and solvents. It withstands extremely high temperatures without changing its color or physical properties.
Storage & Transportation
- Store in tightly closed original packaging in dry, cool, and well-ventilated warehouses, strictly protected from moisture (the product is hygroscopic).
- Keep away from open flames, sparks, and strong heat sources (the material as a dust suspension is a fire and explosion hazard). Observe measures to prevent static electricity buildup.
- When working with powder grades, it is necessary to use personal protective equipment (respirators, thick gloves, goggles), as the product is highly volatile and generates a lot of dust.
- Shelf life: The guaranteed shelf life is usually from 12 to 36 months from the date of manufacture; however, under strict observance of storage conditions (absence of moisture), the product retains its properties for a practically unlimited time.
