The EO-NOZZLE-PROTECT 1.0 from Emil Otto GmbH is a protective fluid designed for soldering nozzles in selective soldering. It forms a film that helps prevent oxidation, dross, and corrosion, which extends the nozzle’s service life. The film also supports steady and accurate solder flow without affecting the soldering process.

The fluid creates a barrier between the soldering nozzle and the solder, preventing particle buildup on the nozzle surface. With regular use, it reduces the need for frequent cleaning and maintenance, saving both time and cost.

By minimizing downtimes and supporting smoother operations, the fluid helps improve productivity and reduce manufacturing costs. It also ensures stable solder flow, leading to clean solder joints and better overall product quality. As Geßner notes, maintaining nozzle condition is essential for efficient machine performance.

The fluid uses a colorless, odorless formula that coats the nozzle outlet with a durable protective film. The fluid is applied using a TIP PEN microliner, which includes a 40 mm metal dosing needle for precise and clean application. Reapplying the fluid regularly helps maintain soldering consistency.

Some of the key features of the EO-NOZZLE-PROTECT 1.0 include:

  • Reduces cleaning and maintenance frequency, saving time and costs
  • Supports stable and precise solder flow for better solder joints and product quality
  • Minimizes downtime and improves overall production efficiency
  • Uses a colorless, odorless formula that is easy to apply
  • Protective film is resistant to chemical, physical, and environmental effects
  • Leaves no residue, does not become sticky or resinous, and prevents deposit formation
  • Free from hazardous substances, ensuring safe handling, storage, and transport

The film resists chemical, physical, and environmental impacts. It leaves no residue, does not become sticky or resinous, and avoids forming deposits. EO-NOZZLE-PROTECT 1.0 is free from hazardous substances, making it safe to handle, store, and transport.
