I founds this on another site about resin max temps
"There has been a great deal of discussion of high temp resins for the composite industry. Some of the non-military markets are the auto exhaust & rocketry/airplane industry.
The questions that are asked are often: what resins exist and what is available. Below is a brief list of the resins produced and some basic info about them.
In temp ranges up to 2000 degrees F, not much is generally available above 500 to 600 degrees F (high temp epoxies) in small quantities (such as gallon sizes).
Feel free to add your knowledge here - especially about high temp resins that are available in gallon sizes or smaller, your favorite high temp resins, non toxic non-brittle resins, and resins available for temps above 600 degrees.
Polyester: temps to 200F, Cheap, Weak, generally available, Good for fiberglass or cosmetic applications
Vinylester: temps to 225F Moderate $, Weaker than Epoxy, Available, Sometimes used as water barrier for polyesters
Epoxy: temps to 600F, generally avail, Used with Carbon, Aramids, &as a water barrier
Polyurethanes: temps to 150F, Cheap, uses harmful isocyanates to cure, Tough, generally not used as composite Matrix
Ceramic Matrix: temps to 3000F+ Moderate $, Generally Brittle, Heavy
Phenolic: temps to 900F,Moderate $, Generally brittle, Fire Resistance
Cyante Esters & BMIs: temps to 565F, Very $$ Poor Avail, Hexcel’s F655, CyCOM-5250-4
Benzoxazines: Poor Avail
Phthalonitriles: Poor Avail
Nanocomposite-enhanced Resins: Very $$, generally not available
Polyimides: Temps to 675F, Very $$, Fairly brittle, hazardous & volatile, ex: LaRC160, PMR15,R P-46, SuperImide"
