Etching titanium with Titan-Etch

Safety

Warm or Cold etching?

There are two methods: Warm etching is the recommended method and is described below. It will produce the most reliable and consistent results. Cold etching does not require heating equipment, but results can be less consistent. Read the instructions for cold etching if you want to try this method.

Supplies & Equipment

Remember: Do NOT use any other materials (e.g. glass and metals) than plastic or titanium for handling and storing Titan-etch. If you do, your etching bath will become contamined and lose it's effectiveness.

Preparing the Titan-Etch solution

Titan-Etch must be dissolved in distilled water to produce the etchant (etching solution). It is important to use the entire bottle of Titan-Etch when mixing it with the distilled water, since the solid ingredients do not mix homogeneously.

Note: the following instructions are based on the use of 250 g Titan-Etch, which produces 1.85 liters of Etchant. For the 500 g bottles of Titan-Etch simply double the amounts of water and Titan-Etch used below.

Etching Preparations

The Etching setup

Reaction time

The reaction time (time you parts are submerged in the etchant) ranges from 15 seconds to more than 5 minutes. The most important factors that determine reaction time are solubility and temperature. It's advised to perform initial test cycles and see which reaction times and etching conditions work best for your parts.
