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 color development in carbon black, but also provides improved color development in other difficult to disperse organic water- and solvent-based pigments. It provides shorter grind times, higher gloss performance, high jetness, low viscosity dispersion and long term viscosity.

Jetness and Pigment Wetting

This carbon black dispersant 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.

Improved jetness in pigments with Borchi® Gen 0451 dispersing agent for carbon black compared to other dispersions. Higher My values indicate increased blackness. Higher Mc values indicate increased jetness of the full pigment color


darkness and undertone with dispersing agent for carbon black pigmentsEnhanced darkness and undertone with Borchi® Gen 0451. Better bluish undertone indicates an overall darker pigment color

better gloss with carbon black dispersant

Borchi® Gen 0451 dispersant 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 size organic pigment and carbon black pigments with lower viscosity and improved dispersion stability. This is how the dispersant ultimately results in better color development for coatings.

Carbon Black Pigment Characteristics and Dispersions

Carbon black pigments are made from the charring of organic substances, including wood and ivory. They are taken 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, dispersing agents like Borchi® Gen 0451 take their dark color to the next level. This provides high quality, clean color in coatings and printing inks.

Similar Dispersing Agents

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

      • 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.
