Afcona 7480

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

High molecular weight polymer

Polymer with high pigment affinity

AFCONA-7480 is recommended for unsaturated polyester, PVC, epoxy,and polyurethaneres in systems.

AFCONA-7480 is mainly used as wetting and dispersing agent, anti-settling agent, to prevent floating, and to stabilize dispersed pigments. AFCONA-7480 also works as an anti-separation additive in multi-resin systems, such as PS (polystyrene) and/or SBS (styrene butadiene rubber) with unsaturated polyester resins.

AFCONA-7480 also has very good wetting power to fiberglass. A system with good fiber wetting will result in better bonding between the fiber and resin, which leads to better mechanical strength of the final product.
