Afcona 7203

Afcona 7203

Fluorocarbon modified polyacrylic

Anti-crater, substrate wetting and leveling agent for solvent-based coatings

AFCONA-3670 is an improved version of AFCONA-3777 on managing surface control of coatings. It has lower surface tension than AFCONA -3777. The combination with a suitable polysiloxane for better overall performance is highly recommended. Due to the fluorocarbon modification, it gives lower surface tension than normal pure acrylic leveling agents. Therefore, it gives better anti-crater and improved substrate wetting.

The obvious performances of AFCONA-3670 are:
1. improve leveling
2. prevent craters
3. help substrate wetting
4. act as a defoamer and de-aeration aid
5. do not interfere with intercoat adhesion

AFCONA-3670 is suitable for all solvent based coatings, especially:
1. baking paints, as leveling and anti-crater agent
2. PU coatings, as leveling, anti-crater and anti inner bubble agent
3. epoxies, as leveling and anti-crater agent

Non-silicone defoamer

Moderate defoamer with fiberglass wetting properties

AFCONA-7203 is mainly recommended for unsaturated polyester and PMMA systems. AFCONA-7203is a moderate defoamer, but it is not recommended for unpigmented/clear systems. Adding AFCONA-7203 to the resin may cause in-can haziness. However, this has a negligible effect on final gloss and will not influence other properties of the system.AFCONA-7203 is a very good defoamer for PMMA solid surface systems with good compatibility and strong defoaming. If AFCONA-7200 or AFCONA-7202 are not providing the desired performance, then a combination with or change to AFCONA-7203 can be a good option because AFCONA-7203 is based on a different chemical composition.AFCONA-7203 shows excellent air release properties in airless spray systems.
