  • Features

    • Develops viscosity stability in water-based coatings mainly in the medium shear range
    • Improves rheological properties of water-based coatings systems for easier brush and roller application
    • Does not yellow or cause chalking in the cured film
    • VOC-free
    • APEO-free
    • Organo tin-free

  • Applications

    • Coatings
      • Acrylic gloss
      • Anti-corrosion
    • Small particle size emulsions

  • Dosage

    • 0.1 – 2.0% on total paint formulation

    Borchi® Gel L 75 N is easy to use and can be added at any stage of the formulation including as a post viscosity adjustment without pre-dilution. Gloss paints may require a higher amount. The exact dosage should be experimentally determined. The thickening action of Borchi® Gel L 75 N may be reduced by polar, water soluble film forming solvents such as alcohols, glycols and glycol ethers. However, low polar solvents such as butyl diglycol acetate and Texanol® will increase the viscosity effect.

  • Storage

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