Castrol 20L Rustilo DWX 21 Corrosion Preventative Oil

Castrol Rustilo™ DWX 21 is a powerful solvent deposited corrosion preventive with excellent dewatering properties. The solvent, after evaporation, leaves an oily protective film. Rustilo DWX 21 rapidly removes water from components subsequent to electroplating processes, after machining using soluble cutting fluids or parts that have been washed. The residual oily film provides effective short-term protection against corrosion on parts and components during intermediate storage or transportation. Although Rustilo DWX 21 can be applied by brushing or spraying, its dewatering action is most effective if the articles to be protected can be immersed in a dip tank.
