Ok Community - I’ve got something I want to etch, but I’m not sure if it’s safe, so I tried reading the MSDS and realized I’m hopeless. Thank goodness I have a community that probably contains some experts who can help.
In essence, I want to try spicing up some etching with a bit of acrylic paint. I know that is commonly lasered, but the first thing I learned is that masking tape will not stick to a surface covered in acrylic paint. It’s got a really smooth feel to it, and even the Gorilla tape just ignores it as a surface. I need masking tape though because I’d like to add a second color, which I would apply to the etching before I weed the tape off.
My solution is to spread a sealant on the acrylic to cover it, and provide a surface tape will adhere to, but I’m not sure if it’s safe to laser the sealant.
TheMSDS for the clearcoat is here, and if anyone could help me to interpret it for Glowforge use I would really appreciate it, and I’m sure others would benefit from the discussion going forward.
I see where there are a lot of fire warnings, but that is what I would expect to see because of the solvent that keeps it liquid. After the sealant is fully cured (I intend to wait at least a couple of days), would it give off harmful fumes if lasered?
Thanks in advance for any recommendations, regarding either the sealant or maybe a better idea to solve the masking problem…
