Quality products for removing oxide from copper strips for surface finishing in strip tinning

Emil Otto produces fluxes and flux concentrates for strip tinning. These are used in particular for the surface finishing of copper strips and copper alloys. The use of fluxes ensures long-lasting, stable connections that meet the most demanding downstream industrial requirements.

Careful preparation of the copper surface is essential to ensure optimum adhesion of a tin coating to copper. Only a flawless surface that is kept free of oxidation and impurities can ensure a durable and reliable bond between the copper and the applied pure tin coating.

At Emil Otto, we offer specially developed flux concentrates that are precisely designed for tinning copper. The fluxes prepare the metal surfaces perfectly and enable uniform, high-quality tinning that meets high industrial standards.

The challenges of strip and galvanic tinning:

A clean, oxide-free surface is required for perfect adhesion of the pure tin. The aim of strip tinning is to achieve a reliable bond between the copper and the applied metal. This bond must be durable and stable. It should not matter how the tin was applied. A uniform coating, whether by strip or electroplating, must be applied precisely and evenly. To meet these requirements, we offer specially developed fluxes. Our products are designed to effectively prepare the copper surface for tinning and ensure excellent wetting properties that enable an even coating.

To achieve this, efficient preparation of the copper surface for pure tin plating is necessary. This is the only way to achieve long-lasting tinning results.

Wide range of applications

In addition to strip tinning, our products offer impressive application flexibility, including for conventional soft soldering of copper materials. Our fluxes for strip tinning can also be used in hot-dip metallizing, a process for surface coating in special applications. Our products for strip tinning can also be used in special applications that require precise and reliable surface treatment.
