TEGOMER® DA 850 is a polymeric copolymer with pigment affinic groups to be used as a dispersant in water-based surroundings. TEGOMER® DA 850 allows to transfer water-based pigment slurries into thermoplastics when water is being evaporated during the extrusion process.
Typical Applications
TEGOMER® DA 850 is a liquid dispersing additive used in the manufacture of water-based pastes of
- Inorganic fillers e.g. talc or barium sulfate, chalk
- Inorganic pigments e.g. titanium dioxide, ultramarine blue, iron oxides
- Organic pigments and carbon blacks
Benefits at a glance
- Higher filling of pastes
- Excellent rheological properties even during long-term storage of pastes
- Prevention of hard settlement of fillers and pigments with high density, e.g. titanium dioxide or barium sulfate
- Improved color strength and covering power
- Less speck formation and agglomerates
- Reduced abrasion properties on the doctor blade used for the application of finishes
- Improved mechanical properties
- Improved durability
- Solvent- and nonylphenol ethoxylate-free
