Dispersant for Transparent Iron Oxide Pigments

Borchi® Gen 1750 wetting and dispersing agent provides excellent dispersions in transparent iron oxide pigments, achieving ultimate transparency for wood and automotive coatings.

This solution is a high molecular weight, VOC-free dispersant and wetting agent for transparent iron oxide pigments. Borchi® Gen 1750 also works well in opaque iron oxides, inorganic pigments, and extenders in water-based systems.

Benefits of Dispersing Agents for Transparent Iron Oxides

Benefits include low paste viscosity, high pigment loading, shorter grind times compared to industry benchmarks, fast attainment of finer particle sizes, high gloss, and excellent storage stability. Small particle sizes result in high transparency. Low viscosity grinds allow for up to 40 % pigment loading for transparent iron oxide dispersions.

Borchi® Gen 1750 dispersant has been tested in transparent iron oxide red and yellow pigments. These include Cappoxyt Yellow 4212X and Cappoxyt Red 4437B from Ferro Corporation.

Applications

Borchi® Gen 1750 is ideal for use in wood and automotive coating applications.

      when combined with Borchi® Gel PN or NA
    • Suitable with with titanium dioxide and other inorganic pigments and fillers

  • Applications

    • Coatings
      • Automotive
      • Wood

  • Dosage

    The exact dosage should be experimentally determined through a ladder study. Borchi® Gen 1750 should be added to the
    mill base before adding the pigment. Active pigment loading:

    • Transparent iron oxide: 50 – 70 %
    • Titanium dioxide: 4 – 8 %
    • Inorganic pigments: 5 – 15 %
    • Organic pigments: 25 – 70 %

  • Storage

    Protect from the effects of weather and store at temperatures between 5 and 40 °C. Once opened, the container should be resealed immediately after each use. The material will become cloudy over time during storage at temperatures below 10 °C
    – this doesn’t affect the performance, but the product should be homogenized before use. The cloudiness can be reversed by heating to room temperature or by heating short term to 40 °C (until clear) without affecting the performance of the product.
