None of the four non vinyl sponge materials tested are considered suitable for application in insulating gun mount shields. Three samples failed under shock test and the fourth became soft at a temperature of 150 F. Only one of the vinyl sponge samples, U.S. Rubber Co. Ensolite 312-1 with U-Sement 512, is suitable for application in insulating gun mount shields. This material meets the requirements of Military Specification R-MIL-I-16562BuOrd. Plastic 52-C-44-II Coating, Strippable Spray Type Adhering Type II is a satisfactory coating for use with insulating materials. It seals in all objectionable odors present in the insulating materials and provides a neat appearing, tough but pliable surface which can take more wear and abuse than the surface of the insulating material. It maintains a very good bond with all vinyl sponge materials tested.
