TEGOMER® DA 855 is a slightly anionic, polymeric wetting and dispersing additive for water-based systems.
TEGOMER® DA 855 is suitable for all kinds of pigments. With organic pigments, outstanding stabilization and viscosity reduction can be observed.
Typical Applications
TEGOMER® DA 855 is a liquid dispersing additive used in the manufacture of water-based pastes and adhesive formulation with:
- Inorganic fillers e.g. talc or barium sulphate, chalk
- Inorganic pigments e.g. titanium dioxide, ultramarine blue, iron oxidesIrganic pigments and carbon blacks
Benefits at a glance
- Increase filler loading of pigment pastes or in adhesive formulations
- Excellent rheological properties even during long-term storage of pastes/formulations
- Prevention of hard settlement of fillers and pigments with high density, e. g. titanium dioxide or barium sulphate
- Improved color strength and covering power
- Reduced abrasion properties (application via a doctor blade)
- Improved mechanical properties
- Improved durability
- Solvent- and nonylphenol ethoxylate-free
