Evaluation of Moisture-Cure Urethane Coatings for Compliance with Industry Specifications

摘要

The Army Corps of Engineers has observed the performance of commercially available moisture-cure coatings on various hydraulic structures over the years, but has had no generic specifications government or private industry for reference in specifying the products. The Society for Protective Coatings (SSPC) recently published specifications for several moisture-cure urethane coatings. However, it cannot be assumed that other commercially available moisture-cure urethanes meet those specifications without confirmation through formal testing. In this project, commercially available products were obtained and tested against the requirements of the SSPC specifications. As a result of this work, new coating systems employing moisture-cure urethane paints were added to the Corps of Engineers Guide Specification UFGS 099702.
