Abstract:

A study was made to find indicators for addition to paints for use on missiles and ship magazines which would undergo color changes upon being exposed to certain fuels. It was desired that the paints be white or of light colors, preferably blue, yellow, or orange. It was also desired that the paints be capable of detecting leaks of hydrazine-based fuels, as well as oxidizers such as fuming nitric acids or halogen compounds. The color responses were desired to be such that an observers attention would be attracted by the contrast, so that he could tell immediately whether fuel or oxidizer was escaping. Lacquers and enamels were developed that undergo vivid color changes upon being exposed to propellants containing substituted hydrazine, nitric acids, or elemental halogens. These paints, which are suitable for use on missiles and missile-storage areas, increased the probability that fuel leaks would be detected before damage occurs. Author
