Cermark/Thermark Thermal Marking Paste

Cermark & Thermark Laser Marking Pastes are similar products used for marking bare metallic surfaces through use of an industrial laser. Both products result in a black ceramic marking which is bonded to the metallic surface through the application of localized heat from the laser. The key differences between Cermark & Thermark are in the liquid base, and the pre-laser coating stability.

Cermark is alcohol-based and results in a stable coating which allows prepped material to be stacked and stored for later laser marking.

Thermark is water-based and results in a powdery coating which is too fragile for storage. Immediate laser marking is recommended.

Part cleanup after laser marking is accomplished with simple water rinse and wiping.
