Many of these conformal coating systems are 2 part, one being the neat resin
, the other being the thinner (solvent). A substitution of the toluene
thinner for a less offensive material (one the alcohol's or Oxsol 100) may
be a solution. The coating manufacturer will likely distance themselves from
this change since it deviates from their technical data sheet. The burden of
qualifying the new process with the solvent change would then fall on you.

Good luck,

Subject: [TN] Humiseal


I have a couple of issues with Humiseal 1A20 that I could use some help
with.

The fumes from this material are making a couple of my employees ill when
they use it
in dip application mode. What are the typical application methods for
Humiseal and how
do you protect your employees from the fumes it produces? According to the
MSDS
it is a suspected carcinogen (toluene), plus a respiratory irritant, and
this has us
concerned. If we switch to a spray coating operation are we going to have to
set up a
dedicated spray booth operation and what are the regulatory concerns with
this,
both safety and environmental?

Thanks for any insight you may provide,
