Since the introduction of the flux concentrates, the product line has continued to develop well at Emil Otto. For this reason, the Hessian flux specialist is once again adding to its list at productronica 2019 and presenting two more flux concentrates at the trade fair.

“Since the fluxing agents of the GSP series have proven very reliable in the domestic market, we were also able to record an increasing number of enquiries from abroad. However it turns out, that with shipment overseas, in some cases the freight costs considerably exceed the value of the goods”, declared Markus Geßner, Marketing and Sales Manager at Emil Otto GmbH. Since these conventional fluxing agents are regarded as hazardous goods in the sense of the transport regulations, requirements had to be met that made the product even more expensive. Shipment per air freight was also impossible, as the flux is only allowed to be packed in small containers. In order to circumvent these problems, Emil Otto developed the flux concentrate GSP-25/AF/OVP, which is suitable as a solution for the spray flux application. A complete package consists of a granulate, which is sufficient for 20 litres of fluxing agent.

Furthermore, Emil Otto will present the flux concentrate EO-B-011B. This is a universal fluxing agent low in solids, that is suitable for wave-, selective- and manual soldering and complies with the specification DIN-EN 61190-1-1: L0. Accordingly, it contains organic, halogen-free activation additives with synthetic resin in a special combination coordinated to the thermal requirements of the soldering processes. EO-B-011B can be applied by brushing, spraying, dipping etc. The solid content is 3 %. EO-B-011B is completely free of corrosion.

Geßner emphasised the benefits of using granulates: “Through the transport optimisation the flux concentrates can be transported economically very attractively over great distances, since the shipping agents charge far lower costs for non-hazardous goods. The flux can be mixed on site very easily. Enclosed with each granulate is the necessary information, which liquid in which dosage must be added to the concentrate. The quantities of granulate are sufficient for 5, 10, or 20l”.

Emil Otto will present the new flux concentrates at the productronica 2019 in Munich in hall A4, booth 420.
