This didn't provide the required deep black needed on 304 stainless using afiber-laser. I found the correct settings, 100% power, -2 mm out out of focus, 20khz (low frequency), 200 mm/sec annealing to be perfect without the spray.
It’s the best I’ve tried the other stuff just washed off after lasering.
I love the results that I get from this spray when using it with my 20 watt diode laser. I hate how costly it is. But that being said I still buy several cans a year for stainless tumblers
Just got my first spray can. First image came out perfect. I was having to sand the bright ss then coat with crt spray and run at 50% and 600 mm/min. Now it’s spray put in my template and hit go perfect results every time. Running at 15% on my NEJE 20 watt and 1500mm/min. This is the cats meow!!!
Works really well easy to use easy to clean up
