Castrol Rustilo DWX 21
01736 757002Castrol Rustilo DWX 21 Dewatering Corrosion Preventive
Castrol Rustilo DWX 21 is a powerful solvent-deposited corrosion preventive with excellent dewatering properties. The solvent, after evaporation, leaves an oily protective film on the metal surface.
Rustilo DWX 21 rapidly removes water from components after electroplating processes, after machining using soluble cutting fluids, or parts that have been washed. The residual oily film provides an effective short-term protection barrier 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
Castrol Rustilo DWX 21 Dewatering Corrosion Preventive Has The Following Advantages:
- Based on a de-aromatised hydrocarbon solvent – mild odour increases operator acceptance
- Free from heavy metals, such as Barium – improves the environmental profile and helps reduce waste disposal cost
- Stable, fingerprint suppressant film characteristics – minimises the risk of corrosion
- Excellent water displacing and penetrating properties and high stability against acidic and alkaline
contaminations – enables a long bath lifetime which helps reduce operational cost

- The claims on film thickness and consumption are average values. These are valid for smooth surfaces with good drain-off characteristics and simple geometries without holes or recesses.
- Average drying time is the time until the majority of the solvent is evaporated at ambient temperature and a relative humidity of 60 – 70%. The full corrosion protection will just be provided when the solvent is completely evaporated.
- “Indoor storage” describes the storage of ferrous components in closed store rooms having a relative humidity of 60%. Increased protection times could be achieved when treating finished surfaces or store the parts in a sealed pack.
- “Outdoor storage” describes open storage, which assumes primary protection from the elements by tarpaulin or other form of cover.
- Influence of temperature may cause some cloudiness, which is reversible and doesn’t have an impact on product quality.
- If required protective films of Rustilo DWX 21 can easily be removed by using a petroleum solvent or alkaline process cleaner, all available from Castrol.
