  • 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.
