Dispersing Agent for Titanium Dioxide and Inorganic Pigments / TiO2 and Inorganic Pigment Dispersant

Borchi® Gen 1252 is a dispersing agent for titanium dioxide in coatings that provides higher inorganic pigment loading, better tint strength, and improved contrast ratios.

This solution is a APEO- and VOC-free high molecular weight dispersing agent for titanium dioxide in coatings. It also works for iron oxides and other inorganic pigments, as well as fillers in water- and solvent-based coating systems.

Dispersant and Rheology Modifier Solutions for TiO2 and other Inorganic Pigments

Viscosity stability is achieved when used with our Borchi® Gel PN rheology modifier. Borchi® Gel PN achieves better viscosity stability than fumed silica for titanium dioxide dispersions. Benefits of using both products together include outstanding anti-settling properties, improved viscosity variance over time after extended heat age stability, no change in gloss or contrast ratio, high opacity and strong tint strength.

Formulation for 2-Week, 50° C Stability Test that includes Borchi® Gen 1252 dispersant, Borchi® Gel PN and Borchers® AF 1171 defoamer significantly enhances settling and flow for TiO2 pigments

Inorganic Pigment and TiO2 Dispersant Applications

While typically used in architectural coatings, this inorganic pigment and TiO2 dispersant can also be used in automotive, industrial, wood and protective and marine coating applications.

Borchi® Gen 1252 has been tested with neutralizers that include AMP-95® from Angus Company.

    • High gloss

  • Applications

    • Coatings
      • Automotive
      • Industrial
      • Architectural
      • Wood
      • Protective and Marine

  • Dosage

    Depending on the pigment grade, the recommended dosage is

    • TiO2: 2-3 %
    • Iron oxides: 5 %

    The exact dosage should be experimentally determined through a ladder study. Borchi® Gen 1252 should be added to the mill base before adding the pigment. Neutralization is required when used in water-based systems as follows, Per 1-part Borchi® Gen 1252:

    • AMP-90®: 0.041
    • AMP-95®: 0.038
    • DMEA: 0.037
    • TEA: 0.041

  • Storage

    Protect from the effects of weather and store at temperatures between 5 and 30 °C. At temperatures below 15 °C turbidity and flocculation may occur. This effect is reversible and does not influence the product efficiency, so warm up to room temperature and mix well before use. Once opened, containers should be resealed immediately after each removal of the product.
