Pat-Add DA 861
- CASE Ingredients Functions
- Dispersant
PAT-ADD DA 861 is a polymeric dispersing agent for solvent-borne, solvent-free, and aqueous paints, inks and colorants. PAT-ADD DA 861 is free of volatile organic components. PAT-ADD DA 861 is multifunctional and compatible with a wide range of non-polar and polar solvent- borne paint systems. Although, PAT-ADD DA 861 is multifunctional and applicable to most pigments, it is particularly effective as a dispersant for carbon black.

- Properties
PAT-ADD DA 861 is a polymeric dispersing additive exhibiting strong adsorption onto a wide variety of pigment surfaces, contributing to excellent dispersion stability. PAT-ADD DA 861 is strongly adsorbed onto inorganic pigments and extenders, contributing to enhanced steric stabilization against re-flocculation. PAT-ADD DA 861 replaces PAT-ADD DA 801 in cases where very low VOC and odor requirements are required.
- Shelf LIfe
The product has shelf life of 24 months from the date of manufacturing; packed in un opened original containers as shipped by Patcham when stored in frost free warehouse.

- Addition and Dosage
The optimal amount of PAT-ADD DA 861 is system related, generally between 0.4 and 1.5% as supplied on total weight of paint formulation. The product is added to the mill-base prior to the dispersion process. For use as dispersing agent in inks, a dosage between 0.7 to 3.0% on total weight of the ink, is typically required. For use in pigment concentrates and colorants higher levels are suggested, such as 3 to 10% PAT-ADD DA 861 on total weight of the pigment dispersion formula. The optimum concentration depends on the individual formulation and best determined with a ladder study.
- HIGHLIGHTS
