Afcona -4401

Afcona -4401 by Afcona Additives is a high molecular weight modified polyacrylic polymer. Acts as a dispersant for deflocculation of all type of pigments. Has very good stability performance, through effective steric hindrance, on all type of pigments. Offers improved gloss and DOI, reduced flooding problems as well as high color strength. Shows a wide compatibility, from low polar to high polar systems, including nitrocellulose and thermoplastic acrylic. Care must be taken with Afcona -4401 as it has a tendency to yellowing or gelling when used in combination with chlorinated polymers and/or epoxies. Exhibits high thixotropy milling pastes, which also results in higher milling viscosity. Used in all kinds of high quality solvent-based industrial coatings including automotive topcoats. Addition and dosage: Calculation method for the required amount of active ingredient on pigment: TiO2 : 2 - 3%, Other inorganic pigments : 2 - 4%, Organic pigments : 20 - 40%, Carbon blacks : 20 - 60%.
