 | As part of the Surface Cleanliness Verification project, sponsored by the Strategic Environmental Research and Development Program, the Naval Facilities Engineering Service Center conducted an investigation of grazing- angle reflectance Fourier Transform Infrared (FTIR) Spectroscopy as a tool for online cleanliness verification at DOD maintenance and repair facilities. In the project's first year, the feasibility of grazing-angle reflectance FTIR was demonstrated in the laboratory for the detection of organic contaminant ... |

| The objective of this project was to determine the durability under accelerated salt-fog exposure of six commercially available composites. These composites included glass- reinforced vinylesters, polyesters, phenolics, and an epoxy. Durability was measured mainly in terms of the loss of elastic modulus and flexural strength after exposure. In order to accelerate aging, the specimens were subjected to temperatures of 95F (35C), 120F (49C), and 160F (71C) for one, two and ... |

|
| A feasibility study on the use of Moisture Cured Urethane (MCU) coatings for large antenna towers was conducted. Results are as follows: (1) MCU coating systems are performing well on Oregon's coastal bridges, (2) MCU coatings will produce a somewhat acceptable bond to either a damp or wet substrate, (3) MCU coatings form excellent bonds to both blasted steel and to MCU intercoats, (4) Aliphatic MCU topcoats exhibit a decrease ... |
