Emil Otto introduces flux concentrates for strip tinning

The new flux concentrates EO-M-023 and EO-M-024 from Emil Otto GmbH, a leading supplier of flux and surface technology, have been developed for the continuous surface refinement of copper and brass strips and wires with pure tin, Sn/Pb and other Sn alloys. The main areas of application are in strip tinning and radiator construction. The fluxes differ in their bromide content and do not contain any heavy metal compounds such as zinc or zinc ammonium chloride. They are also free from zinc, copper and iron ions. Both EO-M-023 and EO-M-024 consist of inorganic-organic halogen compounds. The fluxes are characterized by their ability to dissolve oxides spontaneously and intensively, while they gradually decompose at temperatures of around 230-280°C. Thanks to an adapted process, hardly any residues remain. The EO-M-023 and EO-M-024 combine these properties and thus enable intensive oxide dissolution with a low-residue process. This guarantees a clean and reliable surface finish.

Flux concentrates for soldering in strip tinning and radiator construction

According to the manufacturer, both flux concentrates EO-M-023 and EO-M-024 are characterized by a high throughput rate and fast drying. "Both fluxes are fully miscible with water," emphasizes Markus Geßner, Head of Marketing and Sales at Emil Otto GmbH. The application dilutions range from 1:1 to 1:12 and can be adapted to the respective, specific process requirements. As the EO-M-023 and EO-M-024 are characterized by outstanding wetting, material can be saved due to the low consumption. Emil Otto's flux concentrates are liquid concentrates and are particularly interesting for customers who require large quantities or manufacture abroad. The concentrates are mixed to the correct ratio on site by the customer. This means that the concentrate can be transported more cost-effectively, as the concentrate is shipped in a reduced volume.
