- Product Properties
AFCONA-3580 is an organically modified polysiloxane with very short chain repeatable units of siloxane. Due to the small molecules, they move very fast to a defected area. This gives very good anti-crater properties without any intercoat adhesion problems. AFCONA – 3580 is also widely uses in electroplating and electro deposition coating to avoid crater formation as well as giving a smooth, good leveling and good appearance coating. Itself is not an ionic structure, does it can be use in anionic and cationic system. AFCONA-3580 is recommended to use in all kind of water-based coatings with a pH range of 4 - 10.
The use of AFCONA-3580 gives the following advantages:- Excellent anti-crater behavior
- Improved leveling
- Better substrate wetting
- No intercoat adhesion problems
- Little or no foam stabilization
Note: the slip performance, due to the small molecules, is less.
- Product Properties
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:- Improve leveling
- Prevent craters
- Help substrate wetting
- Act as a defoamer and de-aeration aid
- Do not interfere with intercoat adhesion
AFCONA-3670 is suitable for all solvent based coatings, especially:- Baking paints, as leveling and anti-crater agent
- PU coatings, as leveling, anti-crater and anti inner bubble agent
- Epoxies, as leveling and anti-crater agent
