Afcona 7300

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

Modified polysiloxane leveling agent

Polyether-modified polysiloxane surface modifier

AFCONA-7300is a polysiloxane based polymer. It provides surface leveling, substrate wetting, and improves the slip & glossiness of the finished product. AFCONA-7300 is recommended for unsaturated polyester, PVC, epoxy,and polyurethaneres in systems.AFCONA-7300has a high reactivity to the air interface. It will migrate evenly to the surface to provide good leveling and slip. In pigmented system, AFCONA-7300will provide an even surface tension gradient that resulting in anti-floating and anti-flooding.
