thanks for writing and it's nice to hear someone is doing the work in
the tech as well.
Okay the stuff I got is called Durabond 954-1 and is sold at Cotronics
(New York). about $65 U.S. per pint. $110 per quart.
TM Durabond 7032 2000ºF Stainless Putty (which is practically the same
as the 954)
Now, a 2000ºF Stainless Steel putty that will repair and seal high
equipment with the ease of Cotronics' high performance systems.
A smooth creamy paste, just trowel on and cure at room temperature.
Will not run, drip, or sag.
Safe to use. No flammable solvents. No harsh odors.
Hardening starts in just 60 minutes. (also high temp curing to
increase temp resistance for service)
Durabond 7032 is machinable and resistant to most chemicals and
Durabond 7032 is ideal for high temperature repairs, rebuilding,
plugging leaks in automotive, maintenance and industrial applications.
This composite of Cotronics' unique ceramics and 316 Stainless Steel
to provide excellent adhesion and heat resistance.
7025 Repairs a Wear Plate
I don't know for sure how it will handle with other metals. I am
thinking that steel (general) would be okay, but aluminum, copper and
others I am not sure about. Perhaps Cotronics could answer that
question for you. They have a contact on the website and they also
deliver out catalogues. I got one.
Also look up Resbond 907GF. This actually looks good too. It may
handle the other metals quite well.
Hope that helps and good luck
P.S.: the stuff I got becomes somewhat brittle during temp curing
(100C to 200C). So, expect to lay it one thick for your application or
embed the magnets in this stuff. My rings are done like this and the
magnets do not budge at all. They did before, as I didn't completely
