like the topic? great, isn’t it? didn’t think you’d see something like that here, did you? [:)]
how much temperature can urethane resin stand up to? would a ~500-750 C^o flame licking the part light it up or make it put out fumes? anyone know of a heat resistant resin?
You should probably read the Material Safety Data Sheets for the product. For example I use a lot of Smooth-On 300 series liquid plastic and their MSDS is available on the Smooth-On site
http://www.smooth-on.com/MSDS-PDF/Smooth-Cast%20300%20Series_3.pdf
Note where it says that burning releases toxic byproducts and that firefighters should use self-contained breathing apparatus.
Also, figuring that resin softens enough to become flexible at around the boiling point of water (212 F/100C), at 500 to 750C it will be a molten puddle.
As far as recommending a heat resistant resin, I would recommend you contact the Technical Support people at one of the resin suppliers
At 500 to 750° C it won’t be a puddle—it will be an expanding fireball. Can you say “napalm”? I knew you could.
Are you sure you didn’t mean degrees F? What in the Nether Regions are you using this for? [}:)]

Call me risk averse, but I somehow don’t see this story having a very happy ending.[#oops]
Insert famous Cheech and Chong line here…
While it is possible that there may be some kind of castable, nonmetallic material you can use, there is a reason the real things are made of metal.…
And from the small amount of research I just did, your temperature parameters may be very conservative…
