  • Features

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

  • Applications

    • Coatings
      • E-coat
      • General industrial
      • Automotive primers and basecoats

  • Dosage

    • 0.3 – 0.5 % on total formulation

    Borchi® Gel 0620 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

  • 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. Transportation may cause the incorporation of foam, which has no
    negative influence on application properties. This foam will disappear after gentle stirring.

  • Safety

    The product is not subject to the German Regulation on hazardous material and no labelling is required in accordance with
    the EEC directives. It is not dangerous cargo. Please refer to our safety data sheet for information relating to product safety.
