In addition to the above properties, polyurea presents excellent bonding properties to most materials, especially metals [2].
Materials preparation and characterization In this study polyurea was prepared by using two different fabrication methods.
Specifically, two different materials were prepared by following two different procedures.
All the materials were used as received.
