Afcona 3772

Description

Fluorocarbon modified polyacrylate

Levelling and surface tension reduction agent for aqueous and non-aqueous coatings.

AFCONA-3772 is an acrylic modified fluorocarbon. It contains some carboxylic acid groups, which increase the polarity of the polymer to give good compatibility with most common resins used in coating. For use in aqueous coatings, AFCONA-3772 must be neutralized with a suitable amine. Complete water solubility will be obtained by addition of 9% triethylamine or 12% ammonia solution (25% concentration).

AFCONA-3772:
1) gives no in can haziness
2) provides anti-flooding and floating
3) improves leveling
4) prevents craters and orange-peel
5) helps substrate wetting

In solvent-based coatings, other non-silicone levelling agents like AFCONA –3770, AFCONA –3670 and AFCONA-3777 gives better performance than AFCONA-3772. Due to it good compatibility, AFCONA –3772 is recommended mainly for high gloss clear coatings and as anti inner bubble aid for PU coatings. Like AFCONA –3730, AFCONA –3772 also have very good compatibility with most resin system. However, AFCONA –3730 is much better in leveling and AFCONA –3772 is better in anti-crater and substrate wetting. In clear coating, to obtain all the performances mentioned, we recommended to combine these 2 additives together. For pigmented, matted and primer, we have other products like AFCONA -3670, AFCONA –3770 and etc. that can fulfill all requirements.
