Complete Castrol coverage across the castrol rustilo rust preventives family.
Light oil-film water-displacing rust preventive for short-to-medium-term indoor protection of machined parts and components. Solvent-deposited; flash-evaporates in 5-15 min leaving thin oil film. Indoor protection 3-6 months under stable conditions.
Heavy oil-film water-displacing rust preventives for outdoor or transit protection. DW 901 is solvent-deposited; DW 902 is direct-application. 6-12 months indoor or 3-6 months under transit/outdoor conditions in coastal humidity.
Premium-grade water-displacing rust preventive for long-term storage protection (12-24 months indoor, 6-12 months coastal/outdoor). Heavier oil deposit; suitable for export-stage parts requiring overseas shipment protection.
Water-based aqueous rust preventive for HSE-sensitive plants where solvent-based products are restricted. Indoor short-to-medium-term protection. Compatible with subsequent paint application without solvent flash-off concerns.
Wax-film deposit rust preventive for outdoor parking and yard storage of machinery, gearboxes, motors and structural components. Tough wax barrier 6-18 months. Removable with hot-water wash or solvent before put-in-service.
Specialty short-term indoor protectants for in-process protection between machining operations or at packout. Very thin oil films; no impact on subsequent operations or paint application.
Standard property values across the range. TDS / MSDS / per-batch COA available on enquiry.

Common questions from maintenance + procurement buyers sourcing Castrol Rustilo Rust Preventives through Vasundhara Specialities.
For export-shipment automotive components requiring 3-6 months corrosion protection through container shipment in humid sea-route conditions: Rustilo DW 990 is the recommended grade. Heavier oil-film deposit, salt-spray-tested protection across the typical container-shipment window. For bare ferrous parts (no plating, no paint), DW 990 is the standard. For zinc-plated or phosphated parts, DW 901 may be sufficient.
Rustilo DW range is solvent-carried, oil-film deposit — provides longer-duration indoor and outdoor protection but requires HSE compliance for solvent emissions during application. Rustilo Aqua is water-based, no solvent emissions, suitable for plants where HSE restrictions limit solvent use. Trade-off: shorter protection window than DW range, but better operator comfort and easier paint-line compatibility. Choose DW for tough corrosion environments, Aqua for HSE-sensitive operations.
Rustilo DWX deposits a wax barrier rather than oil film. The wax provides much longer outdoor durability (6-18 months) than oil-film (3-6 months) for parts stored outdoors or yard-parked. Trade-off: the wax must be removed before put-in-service via hot-water wash or solvent, adding a step. Use DWX where the part will be stored outdoors for >3 months and a removal step is acceptable.
Rustilo Aqua is formulated to be paint-compatible — water-based with thin film deposit that flashes off cleanly before paint application. Most plants apply paint without intermediate cleaning when Rustilo Aqua is used. For best results, allow 24 hours between Rustilo Aqua application and paint, and verify paint compatibility with a small-area trial first if specifications are critical.
Rustilo DW 990 provides 12-24 months indoor protection under typical coastal-AP humidity (75-90% RH), assuming sealed packaging or covered storage. Direct exposure to monsoon humidity without packaging shortens this to 6-9 months. For maximum duration, combine DW 990 application with VCI paper wrap or sealed plastic — the combination extends protection to 24-36 months even in tough humidity.
Yes. Castrol Rustilo grades carry per-batch test certificates (corrosion test data, salt-spray hours, film weight), full MSDS documentation, and Castrol India manufacturer authorization. Suitable for ISO 9001 and IATF 16949 automotive-supplier audit requirements. Vasundhara Specialities provides the full documentation pack on enquiry.
For short-term (under 3 months) indoor protection of small components, Rustilo DW 110 light oil-film + sealed packaging is often more cost-effective than VCI paper while providing comparable protection. For longer-duration or outdoor protection, the combination of Rustilo DW range + VCI paper outperforms either alone. Decision is cost + handling — VCI paper is cleaner at unpacking, oil-film requires wipe-down before assembly.
