Castrol Rustilo DWX 30 D, 203L

Castrol Rustilo DWX 30 D is a solvent-based corrosion preventive fluid with excellent water-displacing properties. After the solvent evaporates, it leaves a very thin waxy film that provides medium-term corrosion protection.

Application:

The product is designed to quickly remove water from metal parts after machining, washing or contact with aqueous coolants. It is also recommended for use before electroplating processes and for the protection of brake discs and finished steel components. Maximum dewatering efficiency is achieved when applied by immersion.

Advantages and benefits:

• Effective dewatering: removes moisture even from parts with complex geometry.
• Ultra-thin protective film: does not interfere with measurements or further processing.
• Medium-term protection: up to 9 months indoors, up to 3 months outdoors.
• High stability: bath remains stable even in the presence of acids or alkalis, reducing operating costs.
• Easy removal: protective film can be removed with hydrocarbon-based solvents or alkaline industrial cleaners.

Classification according to standards:

• DIN 51360 – corrosion protection test
• ISO 6743/8 – RK (corrosion preventive oils)

Approvals and recommendations:
VOC compliant (1999/13/EC). Recommended by Castrol for a wide range of industrial corrosion protection applications.

Technical data:
