Afcona 4203

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

Modified polyesterpolymer

High molecular weight polymeric dispersant for all type of pigments.

AFCONA-4203is an result of an innovative concept of polyester dispersants. It is based on the lastest structure of steric hindrance and new designed anchoring groups. Excellent wetting and dispersing performance to Inorganic, organic and carbon black. AFCONA-4203 also can reduce the viscosity of high pigment content paste, and has better stability of concentrates for long time storage. It is very suitable for low VOC formulation design based on it’s solvent-free design.

AFCONA-4203has widely compatibility in common resin systems such as PU, Epoxy, polyester/Melamine, thermosetting acrylic/melamine, alkyd/melamine, acid curing, NC and UV. -AFCONA-4203is suit for producing pastes of all carbon blacks, and it has efficiently viscosity reduction of the pastes.-AFCONA-4203isvery suit for high full-fill, solvent-free systems and printing inks because of its solvent-free design.
