Afcona 3779

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

Pure polyacrylic polymer.

Levelling agent for solvent-based coatings

AFCONA-3779 is a pure polyacrylic leveling agent. Polyacrylic are well known for flow and leveling performance. AFCONA-3779 also acts as defoamer in most coating systems.

AFCONA-3779:
1) improves leveling
2) works as defoamer and deareator
3) provides anti-flooding and floating
4) does not interfere with intercoat adhesion

AFCONA-3779 is especially suitable for:
1) unsaturated polyester
2) coil and can coatings, especially can coating.
3) polyurethane coatings
4) stoving enamels
5) two-pack epoxy compounds
6) air-drying alkyd systems
