Multi-Etch - A Year in Review

Year in review

2020 was a year of sharing our decades of research and expertise with our customers. Click on any of the highlights below to learn more details.

Keeping Etch Times Consistent. You can either etch longer as the bath gets used up or learn how to keep etch times consistent. Here are some helpful tips and links for checking and improving the chemistry throughout the lifetime of the etchant bath.

Hazards of Hydrofluoric Acid. Hydrofluoric acid remains one of the most dangerous substances that can be used. Although Multi-Etch cannot be substituted for HF in oil refinery use, there is a safer option when preparing titanium for anodizing or welding. All of these stories renew our goal of getting the industries that can give up or reduce their use of HF to do so.

Titanium Wall Art using Multi-Etch. By combining a special masking material with titanium anodizing, more complex designs are achievable, resulting in timeless artwork with colors that will never fade!


Overview of the Multi-Etch Process. Do you find yourself with extra time on your hands? This could be the perfect opportunity to investigate Multi-Etch. This blog is great to get an overview of the wide variety of industries that use Multi-Etch.

Brightening Tumbled Titanium with Multi-Etch. Tumble-finishing titanium is a very efficient and fast way to radius (smooth) edges on titanium parts. However, the one drawback is that it leaves the titanium very dark. By using Multi-Etch during and after tumbling, the titanium will be dramatically brighter.

Precision Etching. Since Multi-Etch is not as aggressive as hydrofluoric acid, it excels in removing amounts of titanium as thin as fractions of a micron. This allows for precise removal of material that is difficult to achieve with the blunt action of hydrofluoric acid.


Plastics to use with Multi-Etch. We often stress the importance of using and storing Multi-Etch in plastic containers, never in metal or glass. First time users will receive dry Multi-Etch powder and a plastic gallon jug. This jug is extra robust and perfect for mixing and storing Multi-Etch. Use a funnel to dispense the Multi-Etch powder and distilled or deionized water into the jug. Add a gallon of water for regular strength or 1/2 gallon for double strength Multi-Etch. You can use water heated to 150–160°F in the jug to mix the solution.

Etch Titanium Now, Anodize Later. Sometimes it’s handy to prepare a titanium piece with Multi-Etch and then protect the piece in a way that allows you to set it aside and anodize later. We’ve outlined three successful methods for doing so.
