ELASTOMERS FOR FUEL SYSTEMS CONTAINING MICROORGANISM-CONTROLLING ADDITIVES.
Abstract
An investigation is being conducted to develop aircraft integral fuel tank coatings capable of resisting microbiological deterioration or growth. Jet-fuel microbial isolates were obtained and adapted to growth in contact with fuel and appropriate elastomers. A number of potentially effective biocides are being evaluated in a commercial two-part polyurethane coating. Aluminum corrosion tests are also under way in jet-fuel culture sytems. In connection with this, the possible effect of biocides on aluminum is also being investigated. A need still exists for a completely satisfactory quantitative method for determining the degree of coating deterioration caused by microorganisms. Thus far, microscope techniques appear most satisfactory, with electron-microscope examination being preferable to light-microscope evaluation. Other methods under investigation include the use of the CRC penetration test, electrical-resistance measurements, and penetrating fluorescent dyes. (Author)
