TEGOMER® DA 646 is a wetting and dispersing additive based on polyether technology and can be used as disper sant in liquid or solid concentrates. Furthermore TEGOMER® DA 646 is an emulsifier technology to replace APEO in polymer dispersions.
TEGOMER® DA 646 is a liquid dispersing additive used for the surface treatment of pigments to improve dispersion properties of:
• Organic pigments
• Inorganic fillers e.g. talc
• Inorganic pigments e.g. titanium dioxide, ultramarine blue, iron oxides
TEGOMER® DA 646 can be used for the manufacturing of liquid color pastes, based on oils, polyols or phthalates, containing:
• Organic pigments
• Carbon blacks
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.
