  • Features

    • Develops viscosity stability and improves rheological
      properties mainly in the low shear range
    • Enables application of thick layers on vertical surfaces
    • Effectively prevents sagging
    • Does not yellow or cause chalking in the cured film
    • Free of hazardous air pollutants (HAPs)
    • APEO-free
    • Tin-free

  • Applications

    • Coatings
      • E-Coat
      • General industrial
      • Automotive

  • Dosage

    • 0.2 – 3.0% on total formulation

    Borchi® Gel 0621 is easy to use and can be added at any stage of the formulation. The best incorporation method is to add it
    after the pigment/filler dispersion but prior to being let down. Under low-shear mixing conditions a pre-dilution in water or a
    mixture of water/propylene glycol may be necessary for complete incorporation. The exact dosage should be experimentally
    determined.

  • 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.
