<DIV>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.</DIV>
<DIV> </DIV>
<DIV>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.</DIV>

<DIV>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. </DIV>

<DIV><FONT face=Arial size=2>I sell Dupont brand out of my parts store. A word about the 3m Masks. They are widely and almost exclusively used by all the professional painters in my area. One thing you <STRONG>DO</STRONG> want to do when storing the mask in the re-sealable package <FONT face="Times New Roman" size=3><STRONG>along with cleaning them thouroughly is to remove and dispose of the canister pre-filters. </STRONG>If you do not, the canister will deteriorate just has if a painter would use them everyday. New pre-filters are available from anyone selling the masks.</FONT></FONT></DIV>
