Objectives . Improvement of the technology for obtaining polymer-sprayed coatings based on polycarbodiimides (polyureas) with high chemical, hydrolytic, and abrasive resistance improved physical mechanical properties, as well obtainment polyurea compositions a lifetime at least 5 min without loss performance characteristics (i.e., “hand-applied” polyureas) suitable repair already in use. Method...

Abstract Elastomeric material is used as blast-resistant structure because of its good mechanical properties.A series underwater near-field explosive tests at different standoff distances were conducted to investigate the anti-explosion performance steel structures covered with rubber and polyurea coatings. The experimental results demonstrated that both could enhance blast resistance test plat...
