Interesting to see interest in intumescent coatings.  If you do a search of
archives using 'intumescent, I was advocating this type of product in Nov
2004  and earlier .  Over the years there has been a lot of interest in fire
proof/resistant FRP, but really what is needed is something that will
protect the FRP from the heat.  While resins can be formulated to offer
certain levels of resistance to flammability, it is really the heat the is
the enemy.  Resins quickly lose their strength at tg.  For engine
compartments and the area around the avionics  (inside the fuselage firewall
and forward to the side windows), I highly recommend intumescent coating.
Both of those areas have the means to have a fire supported by a source
other than the resin in the FRP/Carbon Fibre.

Do you have rough cost estimate, what the coating is actually called
"street
name ?" and contact info for Marv at Diemech

Thanks

Jeff.

I thought some of you may be interested in an alternative to the standard
firewall blanket that I, and several others, have used.  It's an intumescent

coating product.  Its used occasionally in the construction industry to
achieve fire ratings on steel structures.  It would be used more but the
cost
is significantly higher than stand fireproofing or wrap assemblies.  It's
only
used when esthetics are a concern and you want to expose the structure.
Diemech Turbines sells it with their Turbine Conversion kit.  It's applied
in
(2) 3/32" thick coats.  When exposed to fire it expands filling voids.  It
allows you to have a really nice finish on your fire wall - if that's of
interest to anyone - it was me.  Don't quote me but I believe the UL rating
for this thickness is 3 hrs and I can't remember at what temps.  I tested a
small section applied to carbon with a touch and it worked.  If you're
interested I'd contact Marv at Diemech for details.
