3M™ Super 77 or Hi-Tack 76?

Salguod

My new egg gaskets came loose so I'm going to replace them with the nomex gaskets. Seems that most people use the 3M Supper 77 adhesive. But a few people talked about 3M™ Hi-Tack 76 Spray Adhesive for high temperature applications.

Has anybody actually tried the high temperature 76? If you have, please respond! It sounds like the way to go since it is made for high temperature. But maybe there is some reason not to use it? Should I should stick with the proven Super 77?

Thanks to all those who have already weighed in on this. Most people seem to be happy with the Super 77 but a few had problems. I was hoping to find someone who has used the high temperature Hi-Tack 76 to get some feed back.

I don't mind doing this, but I would like to have to replace my gaskets only ONCE. So I want to use something that will hold up to repeated cooks.

no problems with the 77 for me!

Super 77 is recommended by BGE and contains FDA approved ingredients. I've gotten my egg up to 800 and have had no problems at all so far.

You can go with the other stuff, but keep in mind that these high temp silicone compounds give off formaldehyde vapors when at high temperatures.

Well, ok then. I guess I'll go with the Super 77 from a food safety standpoint. I was just wondering if anybody had had any experience with the high temp 76. Perhaps a better question would be: Has anybody had an adhesive failure with Super 77?

After reading EVERY post on the nomex gasket, nomex and Super 77 seems to be the way to go. I'm hoping that I can get the nomex WITHOUT the peel away adhesive so that I can use just the Super 77. Another thing, I suppose I might need new bolts after I take the bands off (since the bolts are bent)?

as long as the threads are good, you could get by until you get new bolts. If you tighten to the point of bending, you may have over touqued them too much.

Damn that LC, she did not sign out. That was my post and not LC for the record...

Being a "one and done" type myself, I understand why you would ask. The S-77 is the proven route.

The only failure I'm aware of where Super 77 was used is when it was sprayed on the replacement nomex that included the adhesive. The failure was the adhesive, not the Super 77. I haven't read any reports of the Super 77 failing.

use the same bolts they are supposed to be bent
