Polyurea uses by products of petroleum industry and has been identified as a good candidate material to use as a protective coating or an energy absorber. Over the last few decades, many researchers have investigated the use of polyurea as a protective coating material due to its abilityto absorb a considerably high amount of energy compared tomost other similar coating materials. In recent years, researchershave drawn their attention towards the application of polyuria to enhance the resistance of structures and systems against extremeimpulsive loadings. With adequate surface preparation, polyurea bonds well with most structural materials (such as concrete, steel and aluminium), thereby forming composite behavior. It can be used either as the outer face of a structure, or as an inter layer material, by utilizing its compressive or tensile propertiesdepending upon the nature of the load transmitted.Due to the complex nature of its microstructure, polyuria shows a high level of stress–strain non-linearity, rate sensitivity, and a high degree of pressure dependency compared to otherelastomeric materials. In addition, polyurea has a higher energydensity than most other elastomeric materials. In recent years, aspray-in-place methodology has been introduced for polyuria coating, which has increased its usage in many industrial applicationssuch as tank liners, manhole and tunnel coatings, and secondarycoatings on bridges, roofs and parking decks. Recent studies show that it also possessesthe desired characteristics for effective protective coating applicationagainst blast and ballistic loadings in both vehicles and groundstructures.
