Borchi® Gen WNS

Low molecular weight polyether-modified compound-based wetting and dispersing agent for strong color development with organic pigments. This VOC-free and APEO-free additive is a universal dispersant for water- or glycol-based universal tinting pastes.    
Performance in Organic Blue Pigment Grind for Industrial Coatings
When tested in a Pigment Blue 15:4 grind formulation for waterborne industrial coatings, Borchi® Gen WNS was able to provide improved dispersions at a lower DOP than a high molecular weight dispersant alternative.    

better pigment grind with low molecular weight dispersant

Features

  • Universal dispersant for water- or glycol-based universal tinting pastes
  • Strong color development with organic pigments
  • Improved storage stability

Applications

  • Universal tinting systems
  • Coatings
    • Architectural
    • Wood
    • General Industrial

Dosage

The exact dosage should be experimentally determined through a ladder study. Borchi® Gen WNS should be added to the mill base before adding the pigment. Based on active dispersant on pigment:

  • Titanium dioxide: 1 – 3 %
  • Inorganic pigments: 2 – 5 %
  • Organic pigments: 10 – 40 %
  • Carbon blacks: 30 – 60 %

Storage

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