Coatings:
ADD-4047 is a high molecular weight wetting and dispersing agent that has been developed for high performance solvent-based coatings. The higher molecular weight of ADD-4047 compared to ADD-4046 exhibits stronger deflocculation with organic pigments and carbon blacks. It also shows better viscosity reduction in the mill-base as compared to ADD-4046.
ADD-4047 enhances processing of pigment bases during grinding and enables higher pigment loads to be achieved.
This results in:
• Improved color strength
• Lower viscosity
• Higher gloss
• Reduce dispersion time
ADD-4047 is recommended mainly in transportation coatings (OEM and car refinish) but can be used in all kinds of solvent-based coatings as well as pigment concentrates.
ADD-4047 should be incorporated in the mill-base before adding the pigments.
Inorganic pigments: 10% of oil absorption value (solid form)
Organic pigments : 30-50% of BET value (solid form)
Carbon blacks: 15-25% of DBP value (solid form)
Printing Inks:
ADD-4047 has been developed for solvent-based formulations. It can be used in solvent-based liquid inks and pigmented bases.
ADD-4047 will also be effective in UV-curable formulations.
ADD-4047 may be used in screen and gravure printing.
For best results, ADD-4047 should be combined with the pre-blended liquid portion of the mill-base formulation before addition of the pigment

Storage & Handling
- STORAGE, SAFETY & HANDLING
ADD-4047 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. ADD-4047 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet.
