AeroShell Compound 05

Petroleum mixture for protecting metal. DEF STAN 91-38

AeroShell Compound 05 is a petroleum jelly/beeswax mixture for protecting metal parts against corrosion under temperate and tropical conditions. Specification DEF STAN 80-85 requires the product to have the following approximate composition:

- High melting point mineral jelly (DEF STAN 91-38) 90% mass
- Beeswax (CS.2177) 10% mass.

APPLICATIONS
AeroShell Compound 05 is used for protecting piston assemblies, antifriction bearings, chains and other small parts under temperate and tropical conditions. AeroShell Compound 05 is applied by hot dipping in melted material to give a film about 0.5 mm thick, the thickness can be controlled by the temperature and period of immersion. This gives a fairly firm, greasy film, with a slightly higher melting point, better texture and better protective qualities than plain mineral jelly. Grease resistant wrapping is necessary to protect the film from damage, but parts should be wrapped only after the film has set. The coating should be cleaned off before use, particularly to ensure freedom from grit and dirt, but meticulous cleaning is not necessary as any residual material will normally disperse harmlessly in the lubricant.
