There are about 35 kinds of paint vapors in today's products. There are lots of chemical cartridge masks on the market for paint vapors. The danger from them can be helped with these types of masks.....but generally they WILL NOT protect you from paint hardeners that contain isocyanates.

If you are spraying 2-part paints, they probably contain isocyanates.

You can also be exposed by sanding partially set up paints, by absorbing it through your skin. This can be contolled using "nitrile" rubber gloves.

It is my understanding that 3M is the only company that has an approved cartidge mask for the isocyanates in hardeners.

The danger is that if the mask is not filtering them out... you can NOT smell them!



If you do a search on the internet you will find that 99% of the sites that have expertise will tell you these few things about isocyanates:

Use a remote air source for breathing!.... Period!

Cover your skin, and especially wet areas like your eyes, as isocyanates will be attracted to moisture.

I have had friends overexposed by the time they are thirty. ...and your body never gets rid of them!

OIl type air compressors produce carbon monoxide, like car exhaust. You cannot use them for an air source.

"Oil-free", or diaphram type air compressers can be used if they are in good condition, but they too can produce carbon monoxide if they are not working right.

Overexposure to isocyanates can be fatal. ....not to mention things like cancer and kidney failure.

Be smart! Buy the equipment and use it.

These paints are great products. Just make sure that you last as long as your paintjobs do!!!
