Afcona 7500

Afcona 7500

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

Acidic functional block polymer

Block polymer with acidic functionality with viscosity depressing properties

AFCONA-7500 is recommended for unsaturated polyester, PVC, epoxies,and polyurethane resin systems.

AFCONA-7500 has very good viscosity depressing properties in highly filled systems. It is very suitable for systems with high filler loads like ATH,or artificial marble systems. AFCONA-7500 is also an effective anti-separation additive form LS/LP systems. Due to it high acidic functionality, AFCONA-7500 also can be used in BMC systems as a viscosity stabilizer. AFCONA-7500also has very good wetting power to fiberglass.
