ASFOSIL-398 is a thick soft film type long term protective applied by hand smearing or by brush on plain surfaces or by hot dipping for spare parts and complicated structures. This gives protection of about 2 years under indoor conditions and the film can be easily removed by kerosene or turpentine whenever desired. ASFOSIL-398 conforms to IS 6048-1970 specification.
ASFOSIL-398 being a long term rust protective is used on ferrous parts or components requiring protection upto 2 years. It gives lubricity to parts, hence it can also be used on moving parts or components such as camshafts, gears, bearings, etc.
Surfaces should be absolutely clean (free of rust, oil, dust, etc.) prior to the application of ASFOSIL-398. It is applied by smearing it by hand on the parts to be protected. It can also be applied by hot dipping method. Thinner films will be obtained at higher temperatures and vice-versa. For maximum protection it should be used directly without thinning with solvents.
