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-4000 should be incorporated in the mill base before adding the pigments.

- Typical Properties
- Product Properties
AFCONA-4000 is a result of an innovative concept of polyurethane dispersants. This innovative technology is based on an own new developed intermediate monomer and own new developed anchoring groups. AFCONA – 4000 is higher molecular weight version of AFCONA – 4200.
AFCONA – 4000 has below special properties and recommended in below systems.
1) Beside the good compatibility property as AFCONA 4200, AFCONA – 4000 have higher molecular weight and the performance in ordinary systems like Polyurethane, epoxy, baking paint and etc is better than AFCONA – 4200.
2) AFCONA – 4000 can be used to substitute our previous version of Polyurethane dispersant, such as, AFCONA – 4046, AFCONA – 4047 and AFCONA – 4050. However a real substitute is our
AFCONA – 4077. AFCONA – 4000 is recommended:
1) Thermoplastic acrylic
2) CAB containing system
3) Polyurethane
4) Baking paint that based on alkyd, acrylic and saturated polyester.
Note: AFCONA – 4000 will become slightly hazy at temperature below 5℃. Even at -15℃ the slight haze stay the same. This will not influence the dispersing quality.
