LMM6000, a CerMark™ product, is one of TherMark’s two general purpose laser marking inks and is recommended for creating black marks on a variety of metals. LMM6000 has been specially designed to dry in a hard coat which can be handled prior to laser marking without rubbing off. This allows parts coated with LMM6000 to be stored, moved or stacked prior to laser marking. 
 

If you are interested specifically in marking stainless steel, you should choose LMM6000, as it makes the darkest marks on this substrate. However, the process window for LMM6000 is somewhat narrow, so if ease of use is a concern, LMM14 may be a better option and its marks on stainless are not significantly different from LMM6000.

Recommended substrates:
LMM6000 is a somewhat flexible product which is recommended for many metals. The following list is made up of substrates on which LMM6000 works well. This list is not exhaustive, however, so if your substrate does not appear on the list, this does not mean LMM6000 will not mark it.
