Abstract:

A protective and lubricating coating has been developed for use on the M16 submachine gun and other small arms. It protects the M16 submachine gun used by SEAL and UDT personnel during immersion in sea water and exposure to sand, dust, and jungle environment. Treated weapons are ready for immediate use. The preservative-lubricant coating which was developed for this application is a compound of arachidyl-behenyl amine and tetrapropenylsuccinic anhydride, with an oil and a solvent. It is packaged in aerosol cans for field use. The spray penetrates and displaces water from wet surfaces. The dried coating is firm and nontacky but breaks down to a greaselike consistency between moving parts. The consistency of the coating material can be completely controlled by adjustment of the formulation. It is compatible with other lubricants. The coating provides excellent corrosion protection, because the entire solid phase consists of a waxy polar inhibitor. The oil phase, carrying the inhibitor in solution, can creep out to reprotect scratches and worn areas in the coating. Metal specimens and complete weapons were protected from damage during exposure to sea water for 3 days.
