Coatings:
ADD-4401 is a high molecular weight wetting and dispersing agent that has been developed for high performance solvent-based coatings. Due to its high molecular weight and resin-like structure, ADD-4401 does not influence paint binder durability.
ADD-4401 should be used to stabilize difficult pigments (such as Dipyrrolopyrrol pigments ‘DPP’). Pigment grinds with ADD-4401 are fully compatible with pigment grinds containing other high molecular weight dispersants like ADD-4401.
ADD-4401 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
Care must be taken with ADD-4401 as it has a tendency to yellowing or gelling when used in combination with chlorinated polymers. With solvent-free epoxies it has tendency to yellowing.
ADD-4401 is recommended in all kinds of high quality solvent-based industrial coatings including automotive topcoats, as well as in pigment concentrates.
ADD-4401 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-4401 has been developed for solvent-based formulations. It has broad solubility behavior and will be suited to a wide variety of resin systems.

Storage & Handling
- STORAGE, SAFETY & HANDLING
ADD-4401 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-4401 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet.
