What Respirator For Epoxy Primer

[Jwood]

Hey Guys,

I was looking on a hazard and safety sheet for some epoxy primer and it says use a positive pressure respirator, problem is they are expensive. What masks did you use when laying down your Epoxy Primer and how did it work out? Are you still alive?

Also If it is required is it possible to brush the Epoxy Primer on? Or is this a bad idea? Just trying to stay alive.

Thanks,

John

John:
Is that a two part epoxy with a diisocyanate ingredient (look at the MSDS for the toxic ingredients)?
If so, you really need to be careful, get the correct respirator size and cartridge type (check 3M website or call their help line for cartridge type), and check the fit of the mask by putting the mask on, covering the inhalation ports with some disposable gloves or other thin plastic and see if it holds a vacuum when you inhale (indicating mask isn't leaking around edges due to poor fit). Do not use a mask that doesn't fit. If you can do the spraying in a ventilated area with the airflow coming from behind you, all the better. Toluene diisocyanate and other similar chemicals can cause a variety of medical issues, sometimes on the 10th exposure, sometimes on the first, hence the manufacturer guidance to wear positive pressure suplied air.
PM me if you want to discuss.

The way I understand it:
No filters block all isocyanate stuff but it doesn't seem to be that big of a deal with humans. Masks do filter most of the chemicals that can kill you while painting. Most all masks are the same when it comes to 2 part paints. If you are spraying really nasty stuff then bring in fresh air from outside into the mask. A good fit is always important. Always store your mask in a air tight bag. This will keep the carbon from activating and wearing out.

I'd paint outside if you are not going to use a positive pressure respirator. No sense killing yourself or otherwise messing up your lungs, nervous system, etc. Are the fumes/vapors off this process flammable or explosive?

I agree with Bill.
If you are not gonna spend the money to get the right set up needed, at least paint it outside with a good cartridge mask.

Meh...

If its Just plain ol' Epoxy Primer.. Use a decent mask (the best you can easily afford) and dont worry so much about it...

I wont spray any paints or chemicals without proper gear. 2 cents MIke

Thanks everyone, I am convinced I am just going to brush it on outside. It shouldn't matter I am just using it to seal the metal in prep for bondo and sandable primer. Shouldnt be a huge issue.

Thanks aagain.

I have a pretty unlimited supply of these:

GME-P100s
Great for organic solvents and the like. Very pricey.


I also have a fullface MSA mask. Don't tell Uncle Sam what I am using it for

I do this schitt for a living, and this mask does the job for various paints.
