MATERIALS RESEARCH STUDIES 



The tower is used for materials research studies in such 

 fields as: 



Organic coatings 



(organic resins, acrylics, vinyls, 

 epoxies, polyurethanes, etc.) 



Surface treatments 



(anodizing or alodizing of alumi- 

 num, HAE or Dow 17 for magnes- 

 ium alloys) 



Cathodic protection 



Metal alloys 



(nickel or cupronickel) 



Antifouling techniques and toxicants 



(organo metallic compounds, 

 tinbutyltinoxide , chlor ination) 



Phosphorescent and fluorescent coatings of different colors were tested on the 

 tower under varied lighting conditions. The fluorescent yellow and red colors 

 (F and G) were more visible against the sea during the day and the bright blue 

 coatings (H, I, L and M) Shannon No. 20 or 22 were more effective at night.
