LMM-6000 is our laser marking material for metals. LMM-6000 is ethanol based which allows for a faster drying time. It can be used on a variety of bare metal substrates including stainless steel, brass, aluminum, titanium, tin, copper, nickel and many more. If the metal has a lacquered coating, the LMM-6000 marking material will not work.

Using LMM-6000: LMM-6000 is ready to use in aerosol can form. Shake can well before using. Allow the agitator ball to rattle for at least 2 minutes. For best results, use when can is between 70 and 90 degrees F.

Applying: Clean the surface of the metal so it is free of any type of lubricants or oils.
Hold can approximately 8-12 inches from substrate to be sprayed. Depress valve fully during spray. Apply a thin coat of LMM-6000 to the metal, try to apply an even covering. Try to cover the area to be marked with a light spray, using two passes. If the material is applied too thick, it will require more power to make the mark. It is important that LMM-6000 is applied with an even and thin coat. Applying LMM-6000 may require a little practice to get the right coverage. After use, the can nozzle should be cleaned by inverting the can and spraying until mist becomes clear. Any excess material on the nozzle should be cleaned off with water.

Drying: It is important that the LMM-6000 is allowed to dry thoroughly. It can air dry in
about 2 minutes. This process can be sped up by using a drying oven, hair dryer or a heat
lamp.

Marking On Stainless Steel: This step may require some trial and error to optimize your laser
with a particular substrate. Keep in mind that all lasers react differently depending on the
substrate, the type of laser, the lasers' power, dot size and other factors :

If you are using a YAG laser, you will need to use about 20-25 Watts and a writing speed
between 10-20 inches/second. Again, you may need to run several tests to optimize the settings
for your particular laser.

Marking On Aluminum & Brass: Softer Metals require more power or slower speeds to
obtain a permanent mark. We recommend at least a 50 Watt C02 lasers for such metals.

Clean up: Wash with water or a wet towel. After use, the can nozzle should be cleaned by inverting the can and spraying until mist becomes clear. Any excess material on the nozzle should cleaned off with water. Nozzle can be removed and soaked in warm water if spraying difficulty is encountered.
