abstract

This paper discusses the development of a new dual powder system designed to prevent damage during pipeline transportation and installation and thus achieve a lower net installed cost. The development involved the formulation of two new fusion bond epoxies (FBEs), a base layer FBE that gives improved resistance to disbondment, and an improved damage resistant topcoat. This new system gives exceptional resistance to damage at a lower total film thickness than the original dual powder system. Extensive laboratory testing will be presented which has demonstrated the ability of the system to resist disbondment at elevated temperatures and to provide enhanced resistance to mechanical damage. Details of the challenges associated with the development will be presented.
