Afcona 7204

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

Defoamer with Polysiloxane and foam destroying polymers

Very compatible defoamer with excellent defoaming properties.

AFCONA-7204 is recommended for unsaturated polyester, PVC, epoxy, and polyurethaneres in systems. It has strong defoaming properties without the tendency to cause haziness. AFCONA-7204 can be used in all unsaturated polyester applications, but it is especially suitable for transparent applications and for use by resin manufacturers. AFCONA-7204 has very good compatibility with resin.
