Sustainability and innovation in flux development

In response to increasing customer demand for ecological, sustainable products, Emil Otto has developed a broad portfolio of water-based fluxes. As a sustainability-oriented company, we prioritize not only environmentally friendly end products but also eco-conscious production and simplified transportation.

Our “Green Line” products are water-based and fully biodegradable. Since they do not contain hazardous substances, they are not classified as dangerous goods and pose no harm to the environment. This means they can be transported, handled, and stored using conventional methods, offering significant added value for our customers.

Versatile application in PCBA and cable assembly

The products from the “Green Line” series include fluxes specifically designed for wave soldering and are fully compatible with established production systems. Their soldering performance is on par with alcohol-based fluxes, making it easy for companies to switch to water-based fluxes without compromising on quality.

Emil Otto’s water-based fluxes are ideal for various soldering processes in PCBA (Printed Circuit Board Assembly) and cable assembly, providing multiple benefits.

Key benefits of water-based fluxes

Environmentally friendly and sustainable

Water-based fluxes are non-hazardous, non-flammable, and do not contain volatile organic compounds (VOCs). They minimize health risks for employees and reduce the overall environmental impact. Lower occupational safety requirements make them an ideal choice for sustainable electronics manufacturing.

Cost efficiency in electronics production

Since water-based fluxes are not classified as hazardous materials, they reduce costs for transportation, storage, and compliance with safety regulations. In addition, water-based fluxes lead to lower material consumption, reducing waste and optimizing cost efficiency.

High process reliability for future-proof soldering

Water-based fluxes ensure even wetting of solder joints, providing excellent activation even at low temperatures. Their drying times are now comparable to alcohol-based fluxes, ensuring consistent process stability. They guarantee a clean soldering appearance, even in high-precision electronics applications.

Optimized cleaning with water soluble solder flux

Residues left after soldering can be easily removed using water or agents cleaning agents. This eliminates the need for aggressive chemical cleaners, protecting both components and production environments.

Reducing CO₂ emissions and enhancing sustainability

By switching to water-based fluxes, companies actively contribute to environmental protection by conserving natural resources and reducing CO₂ emissions. The elimination of solvents aligns with strict environmental regulations while improving the overall sustainability balance of manufacturing operations.
