Emil Otto introduces new versions of water-based flux

This No-Clean Flux is designed for use in wave, manual, and selective soldering of printed circuit boards. It contains organic, halogen-free activating additives that are specifically tailored to the demands of the soldering process. Following the launch, Emil Otto expanded the range with variants A, B, and C, each featuring different levels of solids content.

"The water-based EO-G-006 has been developed in a combination with lead and lead-free solders that is specially tailored to the thermal requirements of the soldering process," said Markus Geßner, Marketing and Sales Manager at Emil Otto.

EO-G-006 was formulated to improve the application process and offer greater stability than conventional or partially water-based fluxes. Due to growing demand, particularly from European and Asian markets, Emil Otto developed EO-G-006 with a 5% solids content in 2023.

The new variants offer lower solids content, with Version A containing 2%, Version B 3%, and Version C 4%. "With the EO-G-006 series, we have succeeded in developing an extremely clean and very temperature stable flux. By adding special, VOC-free alcohol compounds, the flux has significantly better drying behaviour in the soldering process than other conventional, water-based fluxes. Furthermore, the fluxes in the EO-G-006 series are significantly more stable and less sensitive to cold," added Geßner.

EO-G-006 and its variants A to C are available as concentrates and are biodegradable. As water-based fluxes, they are not classified as hazardous materials, making them easier to transport, store, and handle using standard methods, with the added benefit of lower shipping costs.

The entire Green Line flux range is compatible with all existing soldering systems and delivers results comparable to alcohol-based fluxes, making the transition to environmentally friendly, water-based fluxes straightforward.
