01736 757002Castrol Rustilo DWX 31 Dewatering Corrosion Preventive
Castrol Rustilo DWX 31 is a powerful solvent-deposited corrosion preventive with excellent dewatering properties. The product, following evaporation of the solvent, leaves a soft greasy protective film
Rustilo DWX 31 rapidly removes water from components subsequent to metal treatment processes such as electroplating processes, after machining using soluble cutting fluids or parts that have been washed.
It is suitable for use on cylinder liners, gears, spiral springs, simple hand tools, steel rods and bars etc.
The thin residual film provides effective medium term protection against corrosion during intermediate storage or transportation.
Although Rustilo DWX 31 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 31 Dewatering Corrosion Preventive Advantages:
- Based on 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
- Superior film retention and fingerprint suppressant characteristics – minimises the risk of corrosion
- Excellent water displacing and penetrating properties and high stability against acidic and alkaline contaminations – enable 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 storing 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.
- The influence of temperature may cause some cloudiness or thickening, which is reversible and doesn’t have an impact on product quality.
- If required protective films of Rustilo DWX 31 can easily be removed by using a petroleum solvent or alkaline process cleaner, all available from Castrol.
Storage
All packages should be stored under cover in a ventilated area at ambient temperature. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and the obliteration of drum markings.
Rustilo DWX 31 should not be exposed to hot sun or cold temperature conditions < 9 °C.
