Dispersing Agent for Carbon Black Pigments and Difficult to Disperse Organic Pigments

Borchi® Gen 0451 is a high molecular weight non-ionic and VOC-free dispersing agent for carbon black pigments. This dispersant not only works for better jetness in carbon black pigments, but also improves color development in other difficult to disperse organic pigments in water- and solvent-based systems. It provides shorter grind times, higher gloss performance, high jetness, low viscosity dispersions, and long-term viscosity.

Benefits of Organic Pigment Dispersants

Organic pigments are difficult to disperse due to their small particle sizes. Dispersing agents like Borchi® Gen 0451 are engineered to efficiently disperse these pigments, which ultimately results in enhanced color.


Carbon Black Pigment Characteristics and Dispersions

Carbon black pigments are made from the charring of organic substances, including wood and ivory. Pigments are extracted from the soot of these burned materials.

Typically, carbon black pigments are used in tire and rubber applications. However, these pigments are also ideal for ideal for use in automotive, industrial, and protective and marine coating applications. They can also be used in printing inks.

While carbon black pigments alone have excellent concealing ability, dispersants like Borchi® Gen 0451 take their dark color to the next level. This dispersant provides high quality black color in coatings and printing inks.


Benefits of Carbon Black Dispersants

As a carbon black dispersant, Borchi® Gen 0451 is known for providing high jetness, or an enhanced jet black color, in pigments. High jetness is primarily caused by three wetting mechanisms within the solution: hydrogen bonding, polarized groups, and an electron rich body attracted to carbon black and organic pigments.


Jetness (My) and Hue Dependent Blackness (Mc)

high jetness with Borchi Gen 0451 dispersing agent for carbon black

Jetness is enhanced in carbon black pigments with the use of Borchi® Gen 0451 dispersant compared to other dispersants. Higher My values indicate increased blackness. Higher Mc values indicate increased jetness of the full pigment color


Darkness (L*) and Undertone (b*)darkness and undertone for Borchi Gen 0451 carbon black dispersant

Borchi® Gen 0451 dispersing agent provides enhanced darkness and undertone. Better bluish undertone indicates an overall darker pigment color


20° & 60° Gloss

gloss performance with Borchi Gen 0451 carbon black dispersant

Borchi® Gen 0451 provides the highest gloss performance for carbon black pigments. Higher gloss, or sheen, indicates better durability in coatings with carbon black


Borchi® Gen 0451 is engineered to maximize the interaction and subsequent wetting of difficult to disperse, high surface area organic pigments. Optimized pigment wetting with dispersants will produce smaller particle sizes in organic and carbon black pigments with lower viscosity and improved dispersion stability. This is how the dispersant ultimately results in better color development for coatings.


Similar Dispersing Agents

Other organic pigment dispersants from Borchers include Borchi® Gen 0851 for water-based pigments. Like Borchi® Gen 0451, this dispersing agent effectively disperses difficult to disperse organic pigments, including carbon black pigments, for enhanced color development.



Borchi® Gen 0451 is ideal for use in automotive, industrial, protective and marine, and decorative coating applications. It can also be used in tires and printing inks.

    • Coatings
      • Automotive
      • Industrial
      • Protective and Marine
      • Decorative
    • Printing inks

  • Dosage

    Depending on the pigment grade, the recommended dosage is

    • Organic pigments: 20 – 35 %
    • Medium black: 40 – 50 %
    • High jetness carbon black: 70 – 100 %

    The exact dosage should be experimentally determined through a ladder study. Borchi® Gen 0451 should be added to the mill base before adding the pigment.

  • Storage

    Protect from the effects of weather and store at temperatures between 15 and 30 °C. Turbidity and flocculation may occur if Borchi® Gen 0451 is exposed to temperatures below 15 °C. This effect is reversible and does not affect its potency.

    Warm the material to room temperature and mix well before using. If its viscosity has also increased and it is difficult to handle the material must be heated to 50 °C to return the viscosity to normal. Once opened, containers should be resealed immediately after each removal of the product.
