PR-2930™-LVLC and Coraseal™ Ambient U1800: High Performance Adhesives for Military Application

This paper investigates two high-performance structural adhesives, PR-2930™-LVLC and CORASEAL™ Ambient U1800, classified as Group I under the MIL-PRF-32662 specification, emphasizing their potential role in structural and armor applications. The study highlights the adhesives’ unique properties, including PR-2930-LVLC’s superior adhesion and CORASEAL Ambient U1800’s remarkable combination of strength and flexibility. Rigorous testing, including hot-wet conditioning and elevated temperature assessments, demonstrates their durability under extreme conditions. The paper also details the adhesives’ performance in Mode I and II strength and toughness evaluations, revealing PR-2930-LVLC’s high strength and CORASEAL Ambient U1800’s superior toughness. These findings underscore the potential of these adhesives to enhance performance during high impact-rate events and to support lightweight vehicle design, addressing a significant gap in adhesive technology for military applications.
