Cerdec Marking

Cerdec Metal Marking Solution

The Cerdec Metal Marking Solution will create black engraving on metal using a Co2 laser. The process works like ceramic glaze in that the laser heats the Cerdec Solution and causes it to change color and soak into the metal surface.

The Cerdec Solution is a thick liquid that can be brushed or sprayed on to the surface. Solid black engraving can be created by applying the Cerdec Solution to stainless steel, tool steel, chrome and other uncoated metal surfaces. This process may not be suitable for all metal types. Testing is the only method to ensure success.

The solution is available in 1/2 lb. and 1 lb. containers. 1/2 lb. of solution will cover approximately 1000 square inches of area.

Using Cerdec Metal Marking Solution

Start with clean, uncoated metal. Remove any oil or grease with alcohol or spirits.

Thoroughly stir and mix the Cerdec Solution. The active ingredients will settle to the bottom of the container.

Brush or spray the Cerdec Solution on the metal. It is better to apply a medium and consistent coating rather than a thick and heavy coating. A foam brush from the hardware store works will as an applicator.

Allow 15-20 minutes for air drying of the coating on the metal. The Cerdec Solution will dry to a light tan color.

Engrave the coated metal area using settings of 100% power and a speed setting equivalent to your lasers' rated power. For example, if you have a 25 watt system, use a speed of 50%.

After engraving, wash the unused coating off the metal using water. A soft brush helps to speed the cleaning process.

Other Tips

Over time the Cerdec Solution may tend to dry out. The active ingredients are still present and you can thin the solution by adding denatured alcohol or water.

The Metal Marking Solution will not work with metals that have a clear coat on them.
