Its outstanding properties make Pigment Carbon Black the most commonly used black pigments in the paint, coating and lacquer industry. They are used for masstone coloring in pure black coatings (e.g., in automotive basecoats), for tinting in gray coatings and paints (e.g., in decoration), and for light tinting in transparence coatings (e.g., for metallic effects and wood glazing).
Water Borne Coatings
In water borne coatings non or weak oxidized Pigment Carbon Black are recommended. These Pigment Carbon Black can be stabilized well in the alkaline medium of water borne systems. Best coloristic values and an optimal stability performance can be achieved by using Furnace Pigment Carbon Black with extremely small mean primary particle size and a narrow aggregate distribution
In two different powder coating systems – epoxy/carboxyl-functional polyester hybrid and carboxyl-functional polyester/HAA (beta-hydroxyalkylamide)–the Beilum portfolio of Pigment Carbon Black was evaluated. Depending on the application (masstone coloring or tinting) Furnace Pigment Carbon Black with different mean primary particle sizes were recommended. For a typical powder coating thickness values of 60 μm to 80 μm and Pigment Carbon Black concentration of 1 to 2 percent are sufficient to obtain opaque films. Overall the use of beaded Pigment Carbon Black is favorable due to the low dust and better handling.
