Borchi® Gen 1252 is specially designed for titanium dioxide dispersions (a.k.a TiO2 dispersions), providing high inorganic pigment loading, tint strength and contrast ratios.

This solution is a APEO- and VOC-free high molecular weight dispersant for titanium dioxide, iron oxide and other inorganic pigments and fillers in water- and solvent-based coating systems.

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 no settling, improved viscosity variance over time after extended heat age stability, no change in gloss or contrast ratio, high opacity and strong tint strength.

While typically used in architectural coatings, Borchi® Gen 1252 can also be used in automotive, industrial, wood and protective and marine applications.

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

  • Applications

    • Coatings
      • Automotive
      • Industrial
      • Architectural
      • Wood
      • Protective and Marine
    • Pigment dispersions (esp. TiO2 and iron oxides)

  • Dosage

    Depending on the pigment grade, the recommended dosage is

    • Titanium dioxide: 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.
