Anionic co-polymer with acidic groups
Features & Benefits
- Product Properties
- AFCONA-5285 is an acidic termination of alkyl ethoxylated co-polymer. The acidic group gives very good anchoring effect in base pigments like inorganic as well as matting agents. It will help in viscosity reduction of filler and extender dispersions.
- AFCONA – 5285 has below special properties and recommended in below systems:
1) Very good dispersant for matting agent pastes. Gives better transparency compared to AFCONA – 4010
2) Very good in viscosity reduction. Therefore, suitable as dispersant for high filler loaded systems
3) Also suitable for oil and solvent- based printing inks especially for inorganic pigment and filler dispersions in alcohol rich systems
4) It's also help to reduce the interfacial tension between pigments or extenders and the vehicle. Therefore, it will help to shorten the grinding time
5) It's can be used in all resin systems ranging from none polar to high polar systems like air dry alkyd, acid curing, polyurethane and epoxy
6) It's also suitable for all kind of pigment ranging from inorganic, organic and carbon black. It is also suitable for cogrinding. - Note: AFCONA – 5285 will become hazy or even crystallize at temperatures below 15° C.
Re-heat the material before use if crystallization happens. This will not influence the quality of AFCONA - 5285.
Applications & Uses
- Applications
- Addition and Dosage
Addition and dosage
0.5 - 1.5% based on TiO2 or extenders
3.0 - 5.0% based on other inorganic pigments
10 – 30% based on organic pigment.
For air dry alkyd, the optimal dosage is 0.07% based on total formulation. This dosage
suitable for organic and inorganic pigments in separate grinding or co-grinding.Incorporation
AFCONA - 5285 should be added prior to the pigment dispersion process.

Storage & Handling
- Storage
AFCONA - 5285 should be stored in a cool dry place, preferable at room temperature ≥ 20°C. Haziness and solidification can take place if the temperature dropped below 15°C. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. The expiry date is indicated on the container.
