STRONGBACK GS-561 EPOXY

StrongBack® GS-561 Epoxy

GS–561 is the first of just two components necessary to apply a standard StrongBack composite pipe reinforcement system. The GS–561 is a 2-part epoxy coating, which can be easily applied over a prepared pipe surface, by gloved hand, spatula or straight edged spreader. The epoxy coating acts as a corrosion inhibitor but also and primarily as a load transfer medium, transferring hoop stresses from the damaged pipeline to the second component of the system, the StrongBack tape.

GS–561 is based on a unique blend of liquid epoxy polymer and aliphatic polyamine curing agents which is able to displace water from wet surfaces in order to make a permanent bond. The formulation is solvent-free to ensure safety and maximum technical performance. Kevlar™* fibers are incorporated for reinforcement and viscosity management to achieve high application rates—even underwater—and to provide permanent protection under the most adverse conditions. It uses advanced low toxicity curing agents. GS–561 can be shipped “Non-Regulated” by USDOT, IATA, and IMO.
