EO-M-024 is a special flux concentrate with a high-performance bromide activation system. It does not contain any heavy metal compounds such as zinc or zinc ammonium chloride and is also free of zinc, copper and iron ions, but consists mainly of inorganic-organic halogen compounds. These are characterized by the fact that they dissolve oxides spontaneously and intensively on the one hand, and gradually decompose from approx. 230 – 280 °C on the other, leaving hardly any residues when the process is adapted.
EO-M-024 was specially developed for the continuous surface finishing of copper and brass strips and wires with pure tin, Sn/Pb alloys and other Sn alloys.
The main areas of application are strip tinning and radiator production. Very high throughput rates can be achieved in these processes due to the exceptionally good activation and action properties as well as the reaction speed and the resulting “fast boiling” and fast drying of the flux. The flux also contains specially formulated surface-active additives that offer the advantages of intensive wetting and economical consumption.
Further information on the ingredients (hazardous substances), safe handling, storage, transportation and disposal can be found in the current safety data sheet (SDS, SDS, MSDS).
Recommendations for the processing of EO-M-024:
This concentrated flux is used to produce – by diluting with water – ready-to-use solutions (application concentration) tailored to the respective soldering and tinning process.
In practice, mixing ratios (dilutions with water) in the range 1:1 – 1:20 are known for these applications and process requirements.
However, the optimal dilution depends on the process or the quality and surface condition of the material to be soldered/tinned and must therefore always be determined by the user through appropriate tests.
