01736 757002Castrol Rustilo DW 330 Dewatering corrosion preventive
Castrol Rustilo DW 330 (previously called SafeCoat DW 33) is a high quality solvent deposited corrosion preventive with good dewatering properties. The solvent, after evaporation, leaves a firm greasy protective film.
Rustilo DW 330 is a long term protective for use in severe conditions where a high degree of protection is required. It is ideal for protection of machine tools and components prior to long-term storage or transportation.
The product also shows good water displacing properties. Although Rustilo DW 330 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 DW 330 Dewatering corrosion preventive Advantages:
- Based on low aromatic solvent (aromatic content less than 0.5 %).
- Free from heavy metals, such as Barium.
- Stable film characteristics reduce run-off loss and thus increase process reliability.
- Fingerprint suppressant.
- Good water displacing and penetrating properties.
- High stability against acidic and alkaline contaminations.
- Long bath lifetimes possible.
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 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 by 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.
Influence of temperature may cause some cloudiness, which is reversible and doesn’t have an impact on product quality.
If required protective films of SafeCoat DW 33 can be removed by using a petroleum solvent or alkaline process cleaner, all available from Castrol.
Storage
To avoid product deterioration always keep the container/drum tightly sealed. Store the product in a cool, dry place away from direct sunlight. Prevent exposure to frost and avoid water ingress. For optimum product stability, it is preferable to store the product indoors between 5°C and 45 °C / 41°F and 113°F.
