Sealing saftey with non food grade silicone

Post by Surf bum » November 20th, 2016, 8:34 am

Attaching sfb to vertical cabinet using Permatex.copper 700*. If immediate perimeter of opening is sealed using nomax tape would it create a safe barrier to use a Permatex 81878 Ultra Copper Maximum Temperature RTV Silicone for the remainder of seal?

I would use it. I never have but I use the red stuff and it works great. The CC doesn't get all that hot either

Thanks, have a large surface to fay seal and even after cure time really dont want latent gassing going thru cc when I do burn off. Figured on the nomex to isolate. Plan to do a long slow to 350*burn about a week after sealing.
