Methods for applying a deterrent coating to small arms nitroguanidine propellants are discussed. By using a new dry-coating technique, a uniform coating of organic material can be applied to the surface of the grain however, such organic compounds diffuse through the grain even at room temperature. This was apparent from an examination of grains coated with highly colored materials, e.g., 2-nitrodiphenylamine. Photographs of cross and longitudinal sections taken at intervals show this diffusion. The use of inorganic materials resulted in no diffusion, but no means of applying such agents so as to produce a deterrent effect has been found.
