Product Features
  • In today coating world, polymers containing fluorocarbon is nearly banned in all coating related to electronic application. Afcona – 3758 are mainly developed to replace fluorocarbon modified leveling agent where it gives the same levelling and anti-crater performance.
  • Afcona – 3758 is a special modified polyacrylic polymer. It reduces drastically surface tension of organic coating systems. This, together with good compatibility in most solvent-based systems and with minimal foam stabilizing effect, makes it very effective as an anti-crater and flow control agent for all solvent based coating.
  • The levelling and anti-crater of Afcona – 3758 can be further improve by combine with Afcona any silicone containing or fluorocarbon containing, wherever it permitted, leveling agent. It will further improve the levelling, anti-crater and substrate wetting properties.
