TEGOMER® DA 646 is a wetting and dispersing additive based on polyether technology and can be used as dispersant in liquid or solid concentrates. Furthermore TEGOMER® DA 646 is an emulsifier technology to replace APEO in polymer dispersions.
Typical Applications
TEGOMER® DA 646 is a liquid dispersing additive used for the surface treatment of pigments to improve dispersion properties of:
TEGOMER® DA 646 can be used for the manufacturing of liquid color pastes, based on oils, polyols or phthalates, containing:
Due to its HLB balance the additive is even suitable for the manufacturing of water-based pigment concentrates. These can be used in water-based or hydrophobic let-down systems afterwards.TEGOMER® DA 646 is a primary or secondary emulsifier for the polymerization of acrylates or PVAc.
- Organic pigments
- Inorganic fillers e.g. talc
- Inorganic pigments e.g. titanium dioxide, ultramarine blue, iron oxides

Benefits at a glance
The use of TEGOMER® DA 646 offers several advantages:
Surface treated pigments with TEGOMER® DA 646 can be used in hydrophilic and hydrophobic surroundings.
- High loaded pigment pastes or masterbatches
- Excellent rheological properties without gelling in liquid pastes
- Improved durability
- Higher colour strength
- Less speck formation
- Improved mechanical properties
- Solvent- and nonylphenol ethoxylate-free emulsifier technology
- Pure acrylates as well as those with high EHA content for adhesive formulation reach fine particle size distribution if it is used as emulsifier
- Water pick up of emulsions and pigments/ fillers is lowered
