A FEASIBILITY STUDY OF VISCOUS CHEMICAL LIGHTING SYSTEMS

In fulfillment of the contract objective, a three-component, thixotropic chemical lighting system was developed which is capable of providing a brightness greater than 4.7 foot-lamberts for a period of 30 minutes and a brightness greater than 2.8 foot-lamberts for a period of one hour when applied to grease-coated surfaces. Higher brightnesses and longer lifetimes are obtained on most surfaces in the absence of grease. Since the brightness is proportional to the thickness of the luminescent layer, the brightness can be adjusted to meet most marking requirements by adjusting the thickness of the applied layer. The three components of the system are mobile fluids and are easily mixed. After mixing, the combined system is highly thixotropic; and while the system is mobile under stress to permit its application to surfaces, it does not flow spontaneously. Thus thick stable layers can be applied to vertical or porous surfaces. The storage stabilities of the three components were found to be satisfactory in short-term accelerated stability tests. Although longer-term testing will be required to insure that the stabilities meet practical storage requirements, the results suggest that practical requirements can be accommodated.
