Laser Marking Spray: OMTech's laser marking spray’s innovative formula allows creation of high contrast, permanent black designs on bare metals with your 25W and above CO2 laser engraver, or more vivid designs with your fiber laser. Please note that the spray initially appears white but turns black after laser engraving

Wide Application: Our laser marking fluid works with most metals including aluminum, stainless steel, brass, and many others, letting you personalize jewelry, customize tumblers, serialize tools, and much more

Even Coating: The 13 fluid ounce aerosol can features a clog proof nozzle that sprays the fine-grained agent with even force, leaving a thin and smooth coat of our marking agent on your bare metal surface

Fast Drying: The cadmium-free metal marking ink dries in under 5 minutes, or in only 2 minutes with a hot air blower, ensuring hassle-free and efficient operation even for batch production

Easy Washing: Once your marking is complete, the unmarked excess black spray can be washed off your item with a simple rinse, so you can enjoy and start selling your fresh and unique design right away
