AFCONA 4401 is an effective polymeric dispersant used to stabilize inorganic and organic pigments. It provides excellent stability performance due to its steric hindrance properties. It is a high molecular weight polymeric dispersant which is modified with polyacrylic polymer, and is capable of deflocculation of all types of pigments.

Chemical Family: Polyurethanes (PU)

Functions: Dispersant

End Uses: 2K (2 component) Coating, Solventborne Coating, Top Coat

Compatible Polymers & Resins: Cellulose Acetate Butyrate (CAB), Epoxies (EP), Melamines & Melamine Formaldehydes (MF), Nitrocellulose, Polyurethanes (PU)

Features & Benefits

Product Properties
  • 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.
  • 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.

Applications & Uses

Application Details

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.
