Bond Behavior of Externally Bonded Elastomeric Polyurea Coating Systems

Abstract

The use of elastomeric polyurea coating systems has been an active area of research recently particularly in the field of hardening of structures for security protection and fragmentation reduction. These systems generally have a high elastic deformability and are relatively lightweight. Elastomeric polyureas are known for having rapid set times, very good durability and exceptional adhesion to a variety of surfaces. Studies at Missouri S&T have improved the tensile strength of the plain polyurea systems with the addition of discrete E-glass fibers. This study examines the bond performance of four (4) elastomeric polyurea systems applied to lab-cured concrete specimens to gain an improved understanding of the bond strength of these systems.
