PU adhesive....
.... is old hat; how about NanoFoil? <-- linky
quote:
NanoFoil can be used to bond metals, ceramics, semiconductors, and polymers. It can also bond dramatically dissimilar kinds of materials without
causing the materials to crack.
As the first technology to create strong, large-area metallic joints between ceramic and metal, NanoFoil may be used in the near future to attach
ceramic armor tiles to U.S. Army tanks and trucks. Epoxies are used now, although their bonds are weak and typically fail with a single ballistic hit.
Worse yet, when a single tile is hit, the shock wave causes neighboring armor tiles to pop off.
