Thermark (or Cerdec) when used with laser technologies allows permanent and indelible marks on many materials, including all non-coated metals and some coated metals, glass, marble, ceramics and a few plastics. 

Marks using the Thermark or Cerdec technique are non-intrusive and therefore does not harm the structural integrity of the material making this a perfect marking solution for aerospace, military and governmental industries to identify aircraft parts and all other parts, especially for UID.

The Thermark or Cerdec process is also widely used for marking medical devices since this process always survives passivation, autoclave any salt spray tests.       

Thermark material is similar to Cerdec material and will work the exact same way.  Thermark is grey and is easier to apply then Cerdec and Thermark wipes off easier - That is why we prefer using Thermark.   

Only one laser method in the world will mark anodized aluminum without ablating or damaging an anodized coating.  Thermark tape can be applied on top of the anodized aluminum, then lasered.  The resulting permanent mark does not damage the coating thereby keeping the full protection of the anodize.  Please see photo.   

Using TherMark and CerMark along with your laser marking system -- be it CO2 or "YAG" -- will more often than not result in high image quality, high-contrast, permanent images.

TherMark/CerMark do not wear off and are not susceptible to corrosion. TherMark/CerMark allows the marking of such material as bare glass, bare aluminum, nylon with dark, easy to read images.

TherMark/CerMark is available in various formulations that allow the material to be sprayed, screen printed or brushed onto the surface prior to marking. A TherMark tape is also available.
