ELM/KF is a special soldering flux based on halogen-substituted organic compounds and offers the advantages of a very wide effective temperature range (approx. 150-290°C). Therefore the soldering flux can be used for numerous soldering and tinning processes.

The active substances contained in the ELM-KF flux are water-soluble. This also applies to the flux residues remaining after tinning as long as the product has not been subjected to extremely high thermal loads. Customary washing equipment serves for post-cleaning.

Application (recommended): Dip tinning, braids tinning, special application

Customer added value:

  • 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)
