[TheForge] Possible replacement for ITC 100

[Larry Zoeller]

To all,
I have been working with my local refractory supplier to find a possible
replacement or substitute for ITC 100.  They have recommended Plistix 900F,
the price would be about a third of the cost of ITC 100.
They gave me some to try out in some forges and see how it holds up and how
it compares to other coatings.  I am looking for a couple of people to coat
there forges and let me know how it performers for them.  I am looking for
somebody that uses there forges daily or on a regular bases, there will be
no cost to you I will send the product free and I will take care of the
shipping cost.  Please e-mail me if you are interested in doing this. 
Enclose a little information about the forge that you will be putting it in
and how often you are using it

Below is a quote from one of the engineers that I have been talking to.

" I've looked at the MSDS sheet for ITC 100 and you're right it doesn't say
much.  However from the reported "melting & boiling point" (I'm still not
sure how a ceramic oxide can hacve a boiling point lower than it's melting
point, but hell I've only been a ceramic engineer for 30 yrs) I believe
this material is zirconia (ZrO2) based.
 
I've reviewed some data from other coating companies such as H&S, ZYP and
CRC and some talk about the high emissivity (reflectance) of their coating
and some talk about black body behavior.
 
Most claim emmissivity values of 0.9 to 0.94 (thouth they don't state at
what temperature and emissivity does vary with temp.
 
From Omega Engineering's emissivity reference tables, I get the following
emissivity values for zirconia and white alumina (Plistix 900F):
 
zirconia @ 75F   0.95
alumina @ 75F   0.94
 
zirconia on inconel  800-2000F   0.62-0.45 (decreasing)
alumina on inconel  800-2000F   0.69-0.45 (decreasing)"     end of quote.
 

Thanks
