Well, you’re obviously thinking of Elmer’s. We gots genuine peanut butter here!

A quality epoxy with a uniform .010" thickness between layers.

Nothing.

Mucilage made from unicorn hooves?

[GingisK]

A whole family of epoxies. The real trick is how each adheres to the differing parts. What sticks to titanium might not stick to carbon. Carbon is not particularly cohesive, so I could image the epoxy breaking away with plenty of material still adhering to the epoxy.

5,000 PSI is not difficult to manage until one has a large surface area with which to contend.

None I know of, but any glue that can withstand 4000psi of pressure even a dozen times would sell.

"OceanMate glue: can withstand close to 5000psi of pressure (emergency) and 4000psi repeatedly (temporarily, and applied correctly on compatible materials. See legal statement).

In reality, there are some that at face value are rated that high:

The strongest epoxy glue you can purchase is probably Systemthree’s T-88. This two-part adhesive has a tensile strength of 7000 psi. https://www.conro.com/what-is-the-strongest-epoxy-glue-i-can-purchase/
