OMTech Laser Marking Powder, 4.1 fl. oz. Metal Laser Marking Fluid for CO2 Laser Engraver, High Contrast Laser Marking Ink for Metal, Laser Black Ink Laser Ink Agent for Aluminum Stainless Steel Brass

Excelente artículo, lo recomiendo

No complaints works great easy to use, does only come with 2 applicators for that large of a quantity but other than that I use it in engraving all the time

Despite claims that this works with aluminum it does not. Rather it does, if you are ok with a massive sacrifice of quality. Running my laser near max power and very slow still will not get this to work well with 1/16" thk aluminum plates. The best i could get was partial adhesions that peel off. Works great on stainless though.

I've used this a few times, and while it's loads better than just engraving on stainless steel without anything, this product is just okay. You have to be very careful when applying this product. If there are streaks in the application, there will be streaks in the finished product. Again, this works, and I will use it until it's gone, but I wouldn't purchase again.

I coated an aluminum surface with this and engraved on it (after the coating dried) with my 120W laser on 200 speed and 60% power. The engraving looked how I wanted until I washed off the excess coating. The engraved coating came right off. I have tried this two times and both times the coating engraving came off. I'm disappointed this even though this OM Tech claims that this works on aluminum, it does not. I should have trusted the other review which debunked their claim.

i decided to try the kind of marking that you mixed with 99 alcohol.to be honest, the spray is better. This solution is ok, but leaves streaks. I tried with the foam brush that came with it (way too small), bigger foam brush and a regular paint brush. leaves streaks no matter how careful you apply.this worked fine except for the streaks

ones mixed with water next day never work back again

Very handy. Mix with alcohol, let dry, and laser.
