<DIV><BR></DIV><BR><FONT face=sans-serif size=2>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 face=sans-serif size=2>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><BR><BR>Gray Fowler<BR>Principal Chemical

-------------- </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=3> </FONT> <BR><FONT size=3>Andre'</FONT>

tips</FONT> <BR><BR><FONT face=Arial size=2>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.
