Borchi® Gen 0451 is a high molecular weight non-ionic and VOC-free dispersant for carbon black pigments and improved color development in difficult to disperse organic water- and solvent-based pigments. It provides shorter grind times, high transparency, low viscosity dispersions and long term viscosity.
This dispersant is known for providing high jetness carbon black pigments. As this product can also act as a wetting agent, 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.
Borchi® Gen 0451 is engineered to maximize the interaction and subsequent wetting of difficult to disperse, high surface area organic pigments. Optimized pigment wetting will produce smaller particle size dispersions with lower viscosity and improved dispersion stability, which is how this dispersant ultimately results in better color development for coatings.

- Specifically designed for dispersing difficult organic pigments and carbon black
- Low viscosity dispersions
- High transparency with organic pigments
- Long-term dispersion stability
- Compatible with a wide range of resin systems
- Protective and Marine
- Printing inks
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.
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.
