  • Features

    • Thixotropic additive for use in water-based coatings
      systems whose binders contain free hydroxyl and
      carboxyl groups
    • Develops viscosity in the low shear range to prevent
      settling and separation
    • Improves viscosity stability of a coating after tinting with
      Universal Colorants
    • Can be used as post additive to adjust the final viscosity
      of a formulation
    • VOC-free
    • APEO-free
    • Tin-free

  • Applications

    • Wide range of polymer systems
      • Vinyl acetate
      • Acrylic
      • Styrene acrylic
      • Colloid
      • Surfactant stabilized polymers
    • Coatings
      • Interior
      • Exterior

  • Dosage

    Typical usage levels are 0.5 – 2.0 % as supplied based on the total weight of the formula. In difficult systems it could be
    necessary to increase the dosage up to 5 % (as supplied) on total formulation. The degree of thixotropy will depend on the
    type of reactive groups present in the system, the pH of the coating (ideally between 7.5 and 8.5), the level of the desired gel
    structure and the amount of Borchi® Gel NA used. The exact dosage should be experimentally determined. We recommend
    adding Borchi® Gel NA at the end of the formula under good mixing conditions to prevent gel seeds from forming and to
    develop a homogeneous gel structure.

  • 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.
