Product Features
  • Afcona – 3700 is a highly fluorocarbon modified polyacrylic polymer. It has very low surface tension and therefore, it can substitute and perform as silicones without the side effects of silicones.
  • Afcona - 3700 reduces drastically surface tension of organic coating systems. This, together with good compatibility with most solvent-based systems and minimal foam stabilizing effect, makes it very effective as an anti-crater and flow control agent for all solvent- based coatings.
  • Due to the low surface tension, it gives very good substrate wetting. Normally recommended to combine with a silicone based levelling agent to gives optimum performance on leveling, anti- crater as well as flow control.

Product Applications
  • Afcona – 3700 is widely used especially in refinish topcoats as a good prevention for crater formation caused by different environment on application sites. Beside this, it improves the vertical leveling in this application strongly.
  • Afcona-3700 is an excellent anti-crater and substrate wetting agent. Afcona-3700 is especially suitable for:
    • Stoving enamels based on alkyd, acrylic and polyester resins
    • Polyurethane coatings
    • Two-pack epoxy compounds
    • Air-drying alkyd systems
    • UV coatings
