Afcona 7466

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

Polycarboxylic acid polymer

Polymer with highly functional carboxylic acids. Excellent in anti-settling and anti-floating and anti-flooding

AFCONA-7466 is recommended for unsaturated polyester, PVC, epoxy,and polyurethane resin systems.AFCONA-7466 is excellent in stabilizing compounds that contain color pigments and extenders. It gives better anti-settling (in combination with a suitable rheology agent), anti-floating and anti-flooding.In silicone permitted system, combination with AFCONA –7300 will gives better leveling and smoothness of the surface. The present of silicone will also help the anti-floating and anti-flooding properties.
