Afcona 3777 is a liquid additive designed for solvent-based coatings, offering anti-cratering, substrate wetting, and leveling properties. It is compatible with various polymers, such as epoxies (EP), nitrocellulose, and polyurethanes (PU), making it suitable for metal and wood substrates. This silicone-free formulation ensures high gloss, improved substrate wetting, and low surface tension, enhancing the quality of the coatings. Its chemical composition includes fluorocarbon components, and it comes in a convenient liquid form for easy application.

Product Properties

AFCONA-3777 is the 1st generation of fluorocarbon modified polyacrylic. Recommended as non-silicone leveling agent where silicone is not permitted due to intercoat adhesion problems. However, we highly recommend a combination with a suitable polysiloxane for better overall performance.
Note: AFCONA-3777 is one of the first developments of fluorocarbon modified acrylics and therefore later developments of AFCONA show improved performances.

Due to the fluorocarbon modification, it gives lower surface tension than normal pure polyacrylic leveling agents and therefore it gives better anti-crater performance and substrate wetting.
AFCONA-3777:

  1. Improves leveling
  2. Prevents craters
  3. Helps substrate wetting
  4. Does not interfere with intercoat adhesion


AFCONA-3777 is suitable for all solvent- based coatings especially for:

  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)
