Koolmat + high temp adhesive

[Captain Avgas]

I'm thinking of using Koolmat from ACS on the cabin side of my RV7A firwall to reduce heat. The Koolmat is rated to 1000 degrees F. The only "high" temp temp adhesive ACS stocks (Scotch Grip Adhesive 09-27220) is ony rated to 300 degrees F.

Anybody out there know of a better high temp adhesive for this application.

Don't know anything better, but I doubt you'd need any better. I used plain ol' 3M77, which is only rated to 110F, and I've never had a problem with firewall insulation coming loose in 3 years.
