Product Features
  • Afcona-4598 is the economy version of Afcona – 4595. This is a wetting and dispersing additive for water-based coatings and pigment concentrates. It prevents negative flocculation effects like flooding and floating and improves storage stability.
  • It stabilize pigments through effective steric hindrance and electric repulsion. This results in concentrates that have:
    • Lower viscosities
    • Very stable dispersions
    • Good storage stability
    • High color strength
  • And final coatings which have:
    • No flooding or floating
    • High color strength
    • High gloss
    • Good storage stability
  • Afcona-4598 is completely water-soluble and does not require neutralization.

Product Applications

Afcona-4598 is recommended for all types of pigments. It is also very suitable for transparent iron oxides.

Note: for optimum dispersion use no resin in the grinding phase

Addition and Dosage

Calculation method for the required amount of active ingredient on pigment:

TiO2 4 - 5%
Other inorganic pigments 8 - 12%
Organic pigments 12 - 30%
Carbon blacks 50 - 60%
Transparent Iron Oxides 10 -15%

Afcona-4598 should be incorporated in the mill base before adding the pigments.
