Description
Castrol Rustilo DW 300 X – Dewatering corrosion preventive
Castrol Rustilo™ DW 300 X is a premium quality solvent deposited corrosion preventive with excellent dewatering properties. The solvent, after evaporation, leaves an oily protective film.
Application
- Rustilo DW 300 X rapidly removes water from components subsequent to electroplating processes, machining with a soluble cutting fluid, or parts that have been washed.
- The residual oily film provides effective short-term protection against corrosion during intermediate storage or transportation.
- Although Rustilo DW 300 X 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.
Advantages
- Good operator acceptance as based on a mild odour isoparaffin solvent
- Heavy metals free, (example Barium) which may help you to fulfil aspects of legislative requirements and waste treatment requirements that specify that these chemicals are excluded
- Contains a corrosion inhibitor package suitable for moderate conditions which provides reliable protection of components
- Excellent water displacing and penetrating properties.
- Good stability against acidic and alkaline contaminations which enables a long bath-lifetime to help reducing operational cost.
- If required protective films of Rustilo DW 300 X can easily be removed by using a petroleum solvent or alkaline process cleaner, all available from Castrol
