DELTA-DC® 3047 is a high molecular weight wetting and dispersing additive for solvent-based coatings and solvent-based printing inks. It prevents reflocculation of pigments through steric hindrance and therefore stabilizes the color strength and hue of pigments in paints and pigment concentrates. DELTA-DC® 3047 is preferably used in automotive coatings and high performance solvent-based coatings. It can be used in all kinds of solvent-based coatings as well as pigment concentrates.

Applications and usage:
DELTA-DC® 3047 is a high molecular weight wetting and dispersing agent that has been developed for high performance solvent-based coatings. The higher molecular weight of DELTA-DC® 3047 compared to DELTA-DC® 3046 exhibits stronger deflocculation with organic pigments and carbon blacks. It also shows better viscosity reduction in the mill-base as compared to DELTA-DC® 3046.
DELTA-DC® 3047 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
DELTA-DC® 3047 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.
DELTA-DC® 3047 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)
DELTA-DC® 3047 has been developed for solvent-based formulations. It can be used in solvent-based liquid inks and pigmented bases.
DELTA-DC® 3047 will also be effective in UV-curable formulations. DELTA-DC® 3047 may be used in screen and gravure printing.
For best results, DELTA-DC® 3047 should be combined with the pre-blended liquid portion of the mill-base formulation before addition of the pigment.
Organic pigments :25-50% of BET value (solid form)
Carbon blacks :20% of DBP value (solid form)
Safety and Handling:
DELTA-DC® 3047 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet.
DELTA-DC® 3047 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. The production date is indicated on the container.
