TEGOMER® DA 640 is a liquid dispersing additive used for surface wetting to improve the dispersion properties of-
• Inorganic fillers e.g. talc, barium sulfate
• Inorganic pigments e.g. titanium dioxide, ultramarine blue, iron oxides
• Organic pigments and carbon blacks with higher addition levels
TEGOMER® DA 640 is suitable at lower addition levels to be used as flocculent for inorganic particles only, e.g. titanium dioxide, metal hydroxides. TEGOMER® DA 640 is a primary or secondary emulsifier for the polymerization of acrylates or PVAc.
TEGOMER® DA 640 is an anionic modified polyether to be used for the following main applications-
• Dispersing of fillers, inorganic and organic pigments in water-based systems
• Flocculation of inorganic pigments or fillers even in the presence of a high electrolyte content
• Emulsifier for polymerization TEGOMER® DA 640 is applied as an emulsifier for the polymerization of acrylates or PVAc.
