Hi! So I'm designing a part that has to go over an exhaust of a car (not too near but not too far either) so it's got constant hot air blowing over it. I've been using pre-preg carbon fiber for the part and I was wondering if I could coat it with this:

which I came across while browsing the internet. Was wondering what you guys would think of this if I used it as my surface gel coat for my pre-preg parts.

Thank you!

X-Preg service temp is only 115C ^


The product in the video is basically an epoxy tooling gelcoat, it's intended for high temperature tooling - ie. moulds for pre-preg.

There is no point putting a high temperature surface coat on a laminate that cant handle those same temperatures. If your pre-preg parts cant handle more than 120C then having a surface coat that can handle 200C isn't going to do anything for it.

As the surface coat isn't a heat reflector, good point.

An option is to apply a heat reflective material, such as something from the Zircotec range. They do a self adhesive option.
