Afcona 7202

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

None silicone defoamer

Good defoaming and develop specially for UPE systems

AFCONA –7202is mainly recommended for UPE resin systems. AFCONA –7202 is consider as moderately strong defoamer. Thus it is not suitable for unpigmented/clear systems. Adding AFCONA –7202 in resin may cause in-can haziness however this will has minimum effect on final gloss and will not influence other properties of the system.

AFCONA –7202 is consider as one of the best and efficient deaeration and anti-foam defoamer in UPE system. It is suitable for hand-lay, spray, gelcoat and filament winding, casting and etc.systems.
