Afcona 7472

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-7472 is recommended for unsaturated polyester, PVC, epoxy,and polyurethaneres in systems.In SMC, BMC, and TMC systems, AFCONA-7472 works as ananti-separation agent between different polymers, for example between PS(polystyrene) and/or SBS (styrene butadiene rubber) and the unsaturated polyester binder.

AFCONA-7472 also can be used as a wetting and dispersing agent for extenders and pigments. Especially with carbon black and organic pigments, it results in better tinting strength and color tone. AFCONA-7472 also has very good wetting strength to fiberglass. A system with good fiber wetting results in better bonding with the fiber, which leads to better mechanical strength of the final formed product
