Wetting and Dispersing Agent for Stabilizing Pigments and Fillers with Polar Surfaces
Borchi® Gen 0650 is an anionic, APEO- and VOC-free wetting and dispersing agent for water- and solvent-based coating systems. This dispersant is highly effective in stabilizing pigments and fillers with very polar surfaces. These include titanium dioxide (TiO2), iron oxide, and hydrophilic organic pigments.

Benefits of Dispersing Agents for Pigments and Fillers with Polar Surfaces
Formulators tend to increase polarity in pigments by adding inorganic oxides to improve wetting. However, pigments that have very polar surfaces are difficult to wet using water alone. Wetting and dispersing agents are required to effectively disperse and stabilize these pigments. Not doing so will most likely result in pigment flocculation or agglomeration.
Borchi® Gen 0650 provides low viscosity dispersions to stabilize TiO2, iron oxide, and hydrophilic organic pigments. It is particularly effective in enhancing colors of tinted white and clear alkyd-based coatings.
Borchi® Gen 0650 is ideal for protective and marine and decorative coatings, as well as printing inks.
In adhesive formulations that utilize DIDP plasticizers, Borchi® Gen 0650 effectively disperses TiO2 pigments.
Control Borchi® Gen 0650
Borchi® Gen 0650 shows better stability in a solution than the control dispersant in a adhesive solution with 70% TiO2 concentration after two weeks at 50°C
Control Borchi® Gen 0650
Better white color development is achieved with Borchi® Gen 0650 dispersant in a TiO2 adhesive formulation compared to the control dispersant
Appearance Clear, high-viscous, colorless to yellow liquid Non-volatile content 100 % pH 6 – 7.5 (aqueous solution 10 %) Density 1.02 – 1.06 g/cm3 Viscosity Max. 3,000 mPa.s Solvent(s) NA
- Specifically designed for stabilizing fillers and pigments with polar surfaces like titanium dioxide, iron oxides and hydrophilic organic pigments
- In systems using metal-based catalysts or driers, excessive amounts may result in prolonged open time and pot life due to complex formations with the metal ions
- May significantly improve the color of tinted white and clear alkyd-based coatings
- Low viscosity dispersions
- Protective and Marine
- Printing inks
- Adhesives and sealants
Recommended amounts of Borchi® Gen 0650 in % (supply form) based on pigment content:
- Titanium dioxide: 1 – 4 %
- Inorganic pigments: 5 – 15 %
- Organic pigments: 10 – 30 %
The amount depends on the particle size and surface area of the pigment. The exact dosage should be experimentally determined.
Protect from the effects of weather and store at temperatures between 5 and 30 °C. Slight turbidity may occur during storage but this does not affect the performance of the product. Once opened, containers should be resealed immediately after each removal of the product.
