HEUR Thickener for the Medium Shear Range

Borchi® Gel 0625 is a HEUR rheology modifier (Hydrophobically modified Ethoxylated Urethane copolymer rheology modifier). This solution works well as a medium shear range thickener for improved rheological profiles in coatings. Borchi® Gel 0625 is a VOC-, APEO-, and tin-free non-ionic polyurethane-based thickener for water-based coatings.

  • Features

    • Develops viscosity stability and improves rheological properties mainly in the medium and high shear range
    • Improved storage stability, leveling and application properties
    • Does not yellow or cause chalking in the cured film
    • VOC-free
    • APEO-free
    • Tin-free

  • Applications

    • Coatings
      • Brush and roller
      • E-Coat
      • General industrial
      • Automotive

  • Dosage

    • 0.2 – 3.0% on total formulation

    The exact dosage should be experimentally determined. The best incorporation method is to add it after the pigment/filler dispersion stage 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.

  • 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.
