Afcona 4530

Modified polyurethane polymer.

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%

AFCONA-4530 should be incorporated in the mill base before adding the pigments.

AFCONA-4530 is a polymeric dispersant for stabilizing inorganic and organic pigments in water-based systems. Through effective steric hindrance and electrostatic repulsion an excellent stability performance on all type of pigments is given.

AFCONA-4530 is an innovative polyurethane dispersant for water-based coating. Compared to the common polyacrylic types, it has below better performances:
1) Better color strength
2) Better pigment stability
3) Better color development
4) Less foam formation
5) pH independent
6) VOC free AFCONA-4530 recommended for manufacturing resin free pigment concentrate for decorative as well as for industrial paints. It can be combined with AFCONA – 6225 for better cost saving without compromising any dispersion quality. Please refer to the application section for guide formulations.

Note: AFCONA – 4530 will become slightly hazy at temperatures below 5° C. This will not influence the quality

AFCONA-4530 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 3 years from the date of manufacture. The expiry date is indicated on the container.
