Borchi® Gen 1252 titanium dioxide (TiO2) dispersant provides higher inorganic pigment loading, better tint strength and improved contrast ratios.
This solution is a APEO- and VOC-free high molecular weight dispersant for titanium dioxide. It also works for iron oxides and other inorganic pigments, as well as 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 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.
While typically used in architectural coatings, this TiO2 dispersant 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.

- Dispersing agent for titanium dioxide pigments that provides high tint strength and contrast ratio
- Strong affinity to iron oxide pigments resulting in stable dispersions with excellent color development
- Over 70 % titanium dioxide and 60 % iron oxide pigment loadings are possible with free-flowing viscosities
- Long-term dispersion stability can be achieved when combined with Borchi® Gel PN in water-based systems
- High gloss
- Protective and Marine
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
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.
