| • reduced flooding | |
| • high color strength | |
• broad compatibility from low- to high-polarity systems, including nitrocellulose. | |
| chemical nature | modified polyacrylate |

Application
Efka® PA 4401 is recommended for all kinds of high-quality solventbased industrial coatings including automotive topcoats as well as pigment concentrates.Care should be taken with Efka® PA 4401 because of its tendency to yellowing and gelling when combined with chlorinated polymers. It also has a tendency to yellowing when combined with solvent-free epoxies.
