Afcona 4550

• Afcona-4550 is a polymeric dispersant for stabilizing inorganic and organic pigments in water-based systems. Steric hindrance and electron repulsion offer very good stability performance with all types of pigments. This results in:
  • Better gloss
  • Color strength
  • Flocculation stability
  • Anti-flooding behavior
• Afcona-4550 is pH-independent and offers wide compatibility with most chemistries commonly used in industrial coatings. Afcona-4550 does not influence the water resistance of the coating.
• Afcona-4550 is also recommended for manufacturing of resin-free pigment concentrates for industrial paints.
• At standard operating temperatures, Afcona- 4550 is completely water-soluble and does not require neutralization. However, neutralization will improve the viscosity reduction performance of this product.
• Afcona-4550 is not water-soluble above 60°C (but the solubility will return once the temperature falls below 60°C). Therefore, keep milling temperatures below 60°C.

Note: Afcona – 4550 will become slightly hazy at temperatures below 5° C. This will not influence the performance of the product.

Add Afcona-4550 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:

Afcona-4550 should be incorporated in the mill base before adding the pigments.

Afcona-4550 should be stored in a cool, dry place.
