AFCONA 4550

• 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.

Addition and Dosage : 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:

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

Incorporation : AFCONA-4550 should be incorporated in the mill base before adding the pigments
