Product Properties

AFCONA-4403 is an effective polymeric dispersant for stabilizing inorganic and organic pigments. It has very good stability performance, through effective steric hindrance, on all type of pigments.; This results in:; improved gloss and DOI; reduced flooding problems; high color strength; AFCONA-4403 is a better compatibility version of AFCONA – 4401. With the special modification it gives lower surface tension on the polymer. This character will allow the dispersant easier to penetrate to the surface of the pigment, thus this gives better wetting and faster grinding.; It has very wide compatibility from low polar to high polar systems, including nitrocellulose and Thermoplastic Acrylic. However care must be taken when used in combination with chlorinated polymers and/or epoxies systems, because in these systems it has a tendency to yellowing or gelling; AFCONA-4403 can be used in all kinds of high quality solvent-based industrial coatings including automotive topcoats. The best performance is given in the following resin systems:; Oil free Polyesters; Thermosetting Acrylics; Thermoplastic acrylics; Note1: Due to the linear and symmetry structure, the viscosity reduction property of AFCONA – 4403 is much less than the AFCONA polyurethane type of dispersants.
