Polyurea when used in a composite system with other materials has proven itself to be extremely durable and resilient when used as a wall coating for bomb blast protection.
The video below is a "car bomb" test. It demontsrates a blast in the size, location and scop of an "average" car bomb. The video shows still photos of the coating operation using a composite material system and several grades and formulations of polyurea coatings.
The equipment inside the room are high speed cameras and testing devisec to measure wall deflection. As you will see, the "control" wall with out any coating is decimated in the blast.
The polyurea wall survives and protects all that is within.
