LI101-12 Oz - Aerosol Black Laser Ink for Metals Marking - CO2 Laser - Fiber Laser - YAG, Permanent, High Contrast, Brilliance Laser Inks (1)

Works amazingly well - I’m using a 455nm 40W laser to mark copper. Without the paint, I couldn’t get anything but a faintly discernible mark after 5 passes at 1mm/sec, 100% power. Now getting superb marking at 100% power, 100mm/sec speed, off a single pass. Wish I’d discovered this earlier.

It's expensive but it works. I use it in my laser engraving workshop and produces good results with my CO2 laser

It's ready to engrave in minutes and washes of with water

It appears to work, but I have not done a lot with it yet

Excellent all round service and an A1 item

No where near as hard wearing as I was expectingThe first can came defective, but was replaced with no issuesJust didn't work for me

Works really well with my 12w laser engraver and aluminum alloy coins. Only marks the coins (as intended) but engraving stays on. Used clear coat to ensure engraving does not get damaged.

I did not expect these results. Just awesome. Technically I renewed (personalized) my tumbler. Shake well the can. Spray on the surface. Let it dry. (Do not touch it, it's like a powder). Laser engrave it. Wash with water. Ready!I liked this over a more expensive version as the plunger top is nicer and there is more information provided by this company... amazing customer service, they really went out of their way to help me get the right settings on my laser. Definitely will buy more!

This product is great. From personal experience it works great on aluminum if you add multiple thin layers drying them in between coatings. The more coatings the darker the engraving. For aluminum I use 100% power at 200mm/min on my 10W laser. The engraving initially leaves a white or grey residue embedded in the blackened material which can be removed by running the engraving under warm or hot water while gently rubbing the surface of the blackened engraving until it is not as rough. Since the powder seems to sublimate or deposit into the surface of the aluminum it may leave excess that makes it look light. You want to remove this excess material with the method suggested but you want to avoid scrubbing too vigorously so as to not remove the deposited material entirely exposing the bare aluminum below the engraving in small spots. Don't believe everything you read on the internet, especially when it comes to reading reviews; good products often get a bad rep because people simply haven't taken enough time to learn how to use them to their standards. Took me a while to get the results I was looking for but I sure got them. Practice makes perfect. 10/10.

Is expensive but don't use much product when lasering so would last for a fair while

Works great I don’t have problems using it on 304 stainless steel and entry level diode laser. Very durable, needs good sanding to be removed It fuses great with the materials don’t need to use much of this sprayExpensive? Yes! Does it work good with entry level 6000mw diode laser Yes!I recommend this product.
