Borchi® Gen 0851 is a high molecular weight non-ionic and VOC-free wetting and dispersing agent that provides color pigment dispersion in difficult to disperse organic water-based pigments, including carbon black and Pigment Red 179 pigments. This dispersant also provides improved grind times, low viscosity dispersions and long term viscosity and color stability. Higher transparency can also be achieved.

This solution is engineered to maximize the interaction and subsequent wetting of difficult to disperse, high surface area organic pigments. Optimized wetting will produce smaller particle size color pigment dispersion with lower viscosity and improved dispersion stability. This is how this dispersant ultimately results in better color development for coatings.

Borchi® Gen 0851 is also known as a dispersant for 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. Other carbon black dispersants from Borchers include Borchi® Gen 0451. Unlike Borchi® Gen 0851, this dispersing agent works for both water- and solvent-based organic pigments, including carbon black.

Borchi® Gen 0851 is primarily used in automotive coatings, but it can also be used in industrial, protective and marine, and decorative applications, as well as in printing inks.

  • Applications

    • 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 0851 should be added to the mill base before adding the pigment. 

  • Storage

    Protect from the effects of weathering and light. Store at temperatures between 5 and 30 °C. Once opened, containers should be resealed immediately after each removal of the product.

  • Safety
