What kind of glue is it? What's its name?

mucilage

The 3M temporary adhesives?

... or is it RTV-1 silicone ?

Could be, Beth. That's a good place to start looking. Get back to me as quickly as you can, okay.





Just jokin.

I don't know that one, Ragman. I'll google it. Thanks.

I'm looking for an adhesive that sticks and seals air leaks, not under pressure, but that peels off easily.

Think of that clear to semi clear silicone like material that holds credit cards and the like in place when they are mailed to you. Then you peel off the card from the paper and this stuff peels off from the paper easily too. Or ir sticks to the credit/bank card.

But its adhesive properties aren't super strong or destructive to the material used.

This sounds like the glue you're describing that is used in bulk mail to hold credit cards in place.

The above site says the glue is also known as booger glue or fugitive glue. Here's a wiki on it:

You might also be thinking of the crafting glue used in hot glue guns:

Or something similar to rubber glue:

That's the stuff, BFN.

'Booger glue' - what a perfect name.

Thanks to everyone for their help.

I think that that stuff would be too permanent for the application I'm thinking of, Region but thanks, I'll check it out.

that would be rubber cement...
