Why CerMark Failed to Bond

What could cause CerMark to not bond to a surface?

If the engraved portion on uncoated metal fails to bond, it may be due to insufficient laser power, incorrect focus, or inappropriate laser speed. The metal surface must be free of any contaminants, and the Cermark coating needs to be thin and evenly applied. The coating should be left to dry for 3-5 minutes before laser marking and not force-dried with heat lamps or blowers. Shake the aerosol can thoroughly before use and dilute the CerMark paste with only ethanol at a 1:1 ratio.
