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.
Improved viscosity stability with Borchi® Gen 1252 dispersant and Borchi® Gel PN rheology modifier in 75% TiO2 concentration with various pigments
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.
Appearance Liquid, colorless Non-volatile content 100 % pH 3 – 4 (aqueous solution 10 %) Density 1.13 g/cm3, 23 °C Viscosity Max. 3,500 mPa.s Solvent(s) NA
- TiO2 dispersant 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.
