Afcona 7200

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

Description

Non-silicone defoamer

Very efficient defoamer with fiberglass wetting properties

AFCONA-7200 is recommended for unsaturated polyester, PVC, epoxy, and polyurethane resin systems. AFCONA-7200is a very strong defoamer. It is not suitable for unpigmented/clear systems because of the risk of causing haziness. Adding AFCONA-7200 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. In many high viscosity systems, AFCONA-7200 is effective when other defoamers do not show sufficient performance
