Stan W, here is something that you might want to speak to.
These days I am a potter by profession, and I work with gas and electric
kilns, building, maintaining, and firing them. Operating temperatures
run to 2500 F. A relatively new second generation kiln/boiler coating
called ITC has come on the market that has some really remarkable heat
management properties. The ITC is applied to the interior of kilns to
reduce the heat loss through the kiln walls and retain it within the
kiln to make the kiln more efficient. It also protects the kiln walls
and reduces ablation of kiln wall materials which occurs at those high
temperatures.
The material is quite pricey - starting at $29 for a pint of the ITC 100
which is used to coat kiln interiors - brick and ceramic fiber board.
There are other kinds of ITC for different uses within t he kiln
environment, each making a contribution to the over-all functionality of
the kiln and preserving it in the high heat environment. Here is some of
the product information
BTW, I have no connection with this stuff or the company other than
being a user of the material

I.T.C. Ceramic Coatings
Ceramic Coatings have two purposes. The coatings have the property of
radiating heat more efficiently than the surface onto which they are
sprayed. This results in improved heating efficiency and often a
substantial saving in fuel cost. Ceramic coatings also protect the
materials that they cover from the oxidizing effects of the heat and
corrosive atmospheres, thus extending their lives. Furnace coating for
boilers have been around for more than fifty years and have been
steadily improved. I.T.C. Ceramic Coatings are the newest generation and
are indeed a formidable, high-tech wonder.
ITC 100 HT Ceramic Coating
Recommended for use on all kiln interiors (electric, gas, and wood
kilns), including hard brick, insulating fire brick and fiber blankets.
It is also used to coat burner blocks and burner tips. ITC will:
* Prolong lifetime of kiln
* Prolong lifetime of kiln furniture
* Reduce fuel consumption between 12% & 55%
* Improve lifetime of fiber insulated kilns and prevents fiber
deterioration by forming a protective crust-like surface on fiber
* Increase heat emissivity of kiln furniture and kiln interior, thus
preventing excessive heat loss in all directions, even through
kiln car decks
* Minimize glaze sticking and build-up on gloss kiln refractory items.
* One pint will cover approximately 3 square feet of area in a kiln.
I*TC 213 Ceramic Coating for Metals*
ITC 213 will protect all metal parts (including elements, burners, kiln
frames, and new elements coated before installation). From oxidation to
reduction and other harsh environments such as high temperatures and
proximity to molten metals, molten glass or glazes
******************
All the information about the ITC products can be found at http:\\axner.com
Go through the websites main menu and "Enter the STore", there do a
search for ITC.
I am wondering if these products could be applied to the Vanagon exhaust
system specifically, and possibly other parts, to better protect from
heat and burnout. The ITC 213 could be applied inside the exhaust pipes
to prevent internal burnout and the ITC 100 could be applied to the
outside of the pipes to prevent heat loss, thereby preventing/reducing
heat buildup in the engine compartment and forcing the heat out through
the tailpipe.
The ITC 100 is a soft product and would, I expect, have to be wrapped
with some sort of heat resistant tape. But the ITC would be doing the
heat protection.
Stan, since you work with Ceramic coatings, any commentary you might
have, or anyone else, would be appreciated.
Thanks,
Regards,
