Otto's Original - Quality products since 1901



Metal etching is a daily occurrence in metalworking. In this process, the chemical properties of etchants are used to mark metal surfaces, identify processing steps and label parts. The paint applied with an etching pen is permanent and can only be removed mechanically. This eliminates the need for time-consuming hammering in and engraving of numbers and characters. The high-quality etchants developed by Emil Otto can be used for all metals, as well as hardened and thin-walled metals. The products can be used for industrial applications as well as for craftsmen/trades and are available in different packaging sizes.
