Product Features
  • Afcona-4401 is an effective polymeric dispersant used to stabilize inorganic and organic pigments. Steric hindrance gives it very good stability performance with all type of pigments. This results in:
    • Improved gloss and DOI
    • Reduced flooding problems
    • Higher color strength
  • Afcona-4401 offers wide compatibility with a variety of polarities of systems, including nitrocellulose and thermoplastic acrylic.
  • Care must be taken with Afcona-4401 as it has a tendency to yellow or gel when used in combination with chlorinated polymers and/or epoxies.
  • Afcona-4401 gives high thixotropy milling pastes, which also results in higher milling viscosity.

Product Applications

Afcona-4401 may be used in all kinds of high quality solvent-based industrial coatings, including automotive topcoats. The best performance is seen in the following resin systems:

  • Oil free polyesters
  • Thermosetting acrylics
  • Thermoplastic acrylics
  • Nitrocellulose combinations
  • CAB mixtures

Note: Afcona – 4401 will become slightly hazy at temperatures below 5° C. This will not influence the performance of the product.

Addition and Dosage

Add Afcona-4401 according to the dosages listed below, which should be calculated based on the percent of active ingredient in the dispersant and the weight of pigment in the formula:

TiO2 2 - 3%
Other inorganic pigments 2 - 4%
Organic pigments 20 - 40%
Carbon blacks 20 - 60%
Incorporation

Afcona-4401 should be incorporated in the mill base before adding the pigments.
