Calculation method for the required amount of active ingredient on pigment:
- TiO2 : 2 - 3%
- Other inorganic pigments : 2 - 4%
- Organic pigments : 20 - 40%
- Carbon blacks : 20 - 60%
- Incorporation
AFCONA-4531 should be incorporated in the mill base before adding the pigments.

- Typical Properties
- Product Properties
AFCONA-4531 is a polymeric dispersant for stabilizing inorganic and organic pigments in water and solvent based systems. Through effective steric hindrance and electrostatic repulsion an excellent stability performance on all type of pigments is given.
For Solvent based
AFCONA-4531 is a polar polymer where it gives very good compatibility to difficult polar systems such as NC, wash primer, etc. Pigment paste that based on AFCONA – 4531 gives very easy incorporation property.
For Water based
AFCONA – 4531 should be pre-neutralized before it can be completely soluble in water. Before adding to the mill base, AFCONA - 4531 should be neutralized up to pH 8.5 - 9.0 and complete water-solubility will be obtained by e.g. addition of 8.5% AMP 95.
AFCONA-4531 not recommended for manufacturing of resin free pigment concentrate.
Note: AFCONA – 4531 will become slightly hazy at temperatures below 5° C. This will not influence the quality.
