EO-G-003 is a purely water-based soldering flux for wave and selective soldering. It is ecologically harmless and non-flammable. The EO-G-003 with its soldering-related properties is at least just as good as comparable alcohol-based soldering fluxes.
Application (recommended): Wave soldering (spray fluxing), selective soldering

Customer added value:

  • Non-flammable (no legal restrictions for transport, storage and handling)
  • Very good soldering properties (capillarity, wetting)
  • Broad process window (high thermal stability, good activity over a long interval)
  • Very good residue behaviour (optically very clean, high SIR)
