<br><font size=2 face="sans-serif">There are canisters that will give a 100% respiratory protection. I can go dig up this info tomorrow if anyone wants to know. It has to be a dual rated cartridge, one for organic solvent one for the isocyanate. You cannot rely on vendor data as their only priority is to be able to stand up in court and say, "But Judge-mon, our label clearly states that use of our product guarantees death to the user and renders his sperm only good for the production of birth defects......." </font>
<br>
<br><font size=2 face="sans-serif">Isocyanate can be absorbed through the skin, but not nearly as acute as breathing. Spray outside and remain up wind, let your neighbors enjoy your hobby also.....<br>

<br><font size=3>I guess the pro painters that live with this stuff should all be dead . I havn't seen one yet with a fresh air system , and they work 8-9 hours a day in the paint booth. hmmmmmm.</font>

<br><font size=3>-------------- Original message -------------- </font>
<br><font size=3>This is my understanding also....that there is no canister-type mask that will protect you from isocyanates (i.e., acrylic urethane paints such as PPG Concept), and the only truely safe way to use isocyanate-based paints is with a remote air supply.</font>
<br><font size=3> </font>
<br><font size=3>It is not just inhalation of vapors that is problematic, it is also absorption through eyes and skin. Isocyanate-based paints are dangerous and some folks can have very bad reactions to trace amounts of isocyanates. Err on the side of caution.</font>

<br><font size=2 face="Arial">Clay: What model 3M mask/filter is safe (as stated by 3M) for use with isocyanates? My experience has been Dupont states that a self contained or supplied fresh air system is the only safe way to spray their isocyanate based paints. </font>
