Adhesive Foam Sprayer

A handheld sprayer loaded with a chemical foam that expands and sets within seconds of contact with air, capable of binding an opponent's limbs together or sealing a door, vent, or window shut well enough to buy real time.

The foam is strong but not indefinite - a determined effort or the right solvent will eventually break it down - so it is best used to create a delay rather than a permanent barrier.
