It's a thick liquid, similar in viscosity to toothpaste, that dries to a hard, but very brittle material. It's commonly used in aerospace applications. Typical application is to apply it in a stripe across a nut or screw head and onto the adjacent surface. Any slight rotation of the fastener causes the brittle material to break apart. It's used to spot evidence of loose fasteners due to vibration or damage. It's also used by repair centers to certify their work has not been tampered with. The latter use is similar to the stickers that read "Void If Removed" when peeled off.
