Castrol Aquasafe 21 - Soluble corrosion preventive oil
Castrol Aquasafe™ 21 is a medium viscosity mineral oil, containing film forming additives and coupling agents, supplied as a concentrate for dilution with water prior to use.
Castrol Aquasafe™ 21 is an interoperational medium term corrosion preventive which is used as an emulsion. It leaves an ultra thin, oily film on ferrous components after the evaporation of the water phase. It is particularly recommended for the protection against corrosion of metal components after other aqueous treatments. Aquasafe™ 21 can be applied by immersion, preferably at 50 – 60 °C. Alternatively low pressure spray, hot or cold, could be used.
Solvent-free, complies with EC Solvent Directive (1999/13/EC).
Free from heavy metals, such as Barium.
Stable emulsion up to 80 °C.
Usage even after applications where increased contamination could be expected, e.g. subsequent to heat treatment or electroplating processes.
Very good stability against inorganic salts.
Excellent wetting properties.
