isocyanates in primer?

[Thingdude]

I have everything ready to start spraying primer onto my car but I am trying to figure out all the proper health precautions before I start (first time to paint a car). Right now I will just be spraying PPG epoxy primer and then the high build or sanding primer that I have yet to buy. The labels on the epoxy primer and hardner cans just reccomend a NIOSH approved respirator which is what I have already. I also have new pink and yellow cartridges ready to put on it. One post says they are good for 6-8 hours. If I keep it in a ziplock bag is that 6-8 hours of use or do I need new filters everyday that I paint? I just want to make sure that the respirator is adequate to keep me protected for both primers. Also, I will be painting outside and probably also use a fan to help blow away the mist. Is it just the base and clearcoats then that have isocyanates? One post said painting in an open garage would be ok with a respirator and I will be outside but I don't want to push my luck. Let me know what you all think. Also, where can I get the nitrile or butyl gloves? Thanks

If you have a charcoal filter you'll be fine but make sure you got some eye protection as well.

Hey-
Epoxy primers don't really kill people as fast as urethanes... Either way, it's the charcoal filters that age in hours, so keep the respirator bagged up tight- I use a Folgers coffee can, but ony after I throw the crappy coffee away!

You ought to be fine in the driveway with what you have planned, the garage is also just as fine- it's all in the amount of exposure you give yourself. Walk out in between coats, and if you SMELL the paints and primers as you are working with them, you are taking in some amounts of their toxins... Have fun!

to my kowledge ALL paints contain iso's some more than others. that's the chemical you can't see or smell, if I'm not mistaking and voc's are the ones you can. 3m's 7192 is usually a good cheap filter you can buy to get the job done it's only about 18 bucks and it lasts for 40 hours(total spray time) with your filter set up you should be fine just don't leave it out and yes use it ALL the time,just some useless info for ya,Tim

i know my posting is way after the fact but if it helps someone else then so be it

the disposible resporators (charcoal type)don't remove the isocynates from the air you are breathing in they will remove some of the volital organic compounds (voc's) that's why with urathane paints & primers you need to use a fresh air supply mask
also one thing to remember is you absorb more in through the pores in your skin and your finger nails
