- Properties
PAT-ADD DA 2672 is specially designed to be used as synergist for optimisation of the interaction between polymeric dispersants and pigment surfaces. The product is seldom used alone, but typically used in conjunction with polymeric dispersants such as Pat-Add DA 934 or DA 936. Related to the yellowish color, PAT-ADD DA 2672 is recommended as a dispersion synergist for organic yellow pigments mainly. Applicability on other pigment colors has to be checked individually. Using PAT-ADD DA 2672, results in remarkable reduction of pigment dispersion viscosity, so enabling highest pigment loadings.
- Application
Synergist, for Blue,Black and Violet Pigments, to be used in conjunction with high molecular weight polymeric dispersing agents series.

- Addition and Dosage
PAT-ADD DA 2672 is used in solvent borne systems and performs best if used in conjunction with polymeric pigment dispersants such as Pat-Add DA 934 and other members of the DA 900 series. Typically a ratio of 1 part DA 2672 and 5 to 10 parts of DA 934 is required. Please refer to the recommended dosage of the Pat-Add DA 900 polymeric dispersants first, and use additionally the DA 2672 for optimizing pigment loading and reducing viscosity. PAT-ADD DA 2672 is added to the millbase, well mixed in the liquid, before the addition of the pigments; next step is the milling process.
