Afcona 4720

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 polyacrylate blocked polymer

AFCONA –4720 is a 100% active, solvent-free dispersing agent based on an AB blocked polymer and a group of anchoring agents. Its advanced 3 block high molecular weight structure allows the development of pigment dispersions that show better compatibility in broad applications.

AFCONA-4720 demonstrates the following advantages:-good compatibility across a broad range of binder systems including TPA’s and NC-based systems-recommended for Auto OEM and VR coatings as well as other high performance systems-performance in high jet black dispersions is excellent. Gives very good jetness to difficult high jet black pigments.
