How hot can we get with high temp resin?

I printed a heat gun nozzle out of high temp resin. Since formlabs used to advertise heavily an image of a blowtorch nozzle made out of it with a blue flame spitting through it, I figured it would be a safe try. The heat gun is 750, or 1000 Farenheit depending on low or high setting. I need to know what is the max temp this stuff can take in a static application just for heat flow. I know the heat deflection temp is around 600 farenheit but that is at a specific load, this part wont be under load. Please help!
