- Properties
PAT-ADD DA 1808 is a dispersing agent showing strong adsorption properties onto a wide variety of pigment surfaces, contributing to best dispersion stability. PAT-ADD DA 1808 is strongly adsorbed onto inorganic pigments and extenders, contributing to enhanced sterical stabilization against re-flocculation.
- Benefits
- Optimizes the milling process, enabling high pigment loading
- Provides excellent color development
- Strong prevention of pigment flocculation, floating, flooding, and pigment settling
- Excellent compatibility with alkyd resins, thus minimal risks of causing unwanted side effects
- Minimal effect on heat stability if used in plasticized PVC systems

- Application
Pigment dispersant, mainly for polar pigments, wide range of compatibility. Polyester compound.
- Dosage & Addition
The optimal amount of PAT-ADD DA 1808 to be used is system related, but generally is between 0,3 and 0,8% PAT-ADD DA 1808, calculated on the total weight of paint formulation. The product is added to the mill-base prior to the dispersion process. For use as dispersing agent in plasticizer pastes, a dosage between 0,7 and 3% on total weight of the paste, is typically required. The optimum concentration to be used depends on the individual requirements and conditions.
