Laser Marking Compounds
These compounds can be used to allow easier marking and higher contrast marks with a CO2 laser. The metal marking compounds produce permanent black markings, which are highly resistant to mechanical and chemical stresses as well as high temperatures.
Laser Marking Compounds are available as a paste, spray or tape.The most convenient method is to apply it using a spray can. Brush application is appropriate whenever the entire surface can be coated with a single brush stroke. Spraying the paste, e.g. using an airbrush, is suitable for coating larger areas in a single step. The tape, however, is a particularly clean solution for smaller areas. The plastic marking compound allows for black marks on thermoplastics, while the compounds for ceramics and glass produce coloured marks on these materials (YAG or Fiber laser recommended).
