Afcona 7206

Afcona 7206

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

High molecular weight polymer, silicone free.

AFCONA-7206 can destroy the foams efficiently whenever on the surface or in the solution,and also can improve the compactness of product’s surface film, and improve the weather resistant and chemical resistant, as well as the aesthetics. Widely used in unsaturated polyester, polyacrylate, polyurethane and epoxy systems.

Solvent-free defoamer, is recommended to free radical polymerization systems of unsaturated polyester, vinyl, acrylate and also can be used in epoxy and polyurethane resins. The defoaming performance won’t be affected by the temperature whenever lower or higher. Because of solvent-free, AFCONA 7206 can be used where low VOC required applications.
