Description
Castrol Rustilo Aqua PR may be used as either a white spirits or water-borne corrosion preventive / pressing
lubricant, being a slightly turbid brown liquid in the neat state. The protective film is oily and slightly greasy.
Applications
• Castrol Rustilo Aqua PR has been specifically formulated to meet the body / panel pressing and corrosionprotection
requirements of the motor vehicle manufacturing industry.
Castrol Rustilo Aqua PR represents a major breakthrough in the drawing / rust preventive market, being used
neat as a drawing lubricant on deep drawing or as an emulsion for operations of lesser drawing severity.
Method Of Application
When used as a drawing compound Castrol Rustilo Aqua PR may be applied neat or as an emulsion, (depending
on the severity of the draw). Means of application is by roller, wipe application, etc. Successful deep drawing
operations include box sections, wheel wells, petrol tanks, etc
As A Water-Borne Rust Preventive
Conventional rust preventives work by the process of placing a physical barrier between the metal surface being protected
and the outside environment. With these products, the film-forming material is deposited by evaporation of a volatile
petroleum solvent, the solvent content being as high as 70% - 80%. With Castrol Rustilo Aqua PR, however, the
film-forming material may be deposited in the form of an emulsion with water. On application the emulsion breaks, the
water evaporates and the rust-preventive film is left behind. This is an irreversible process and film will not re-emulsify.
NOTE: Castrol Rustilo Aqua PR may also be mixed with white spirits in place of water, upon which it behaves as a
conventional temporary corrosion preventive.
Advantages
• Consequently reducing stock - holding requirements and saving on inventory costs.
• Very cost-effective - expensive solvents.
• Reduced stock holding - no need to hold flammable solvents in stock.
Safe and pleasant to use.
• Non-polluting to the atmosphere.
• No ventilation required.
• 30% dispersion in water offers approximately 6 months protection indoors.
• Compatible with alkali-wash systems ensuring easy removal from pressed panels with no adverse effect on
further process requirements, E-Coat, etc.
• Dual purpose - may be used as a pressing lubricant / corrosion preventive.
• Ensures reduced product drag-out when used as a pressing lubricant. (Reduced product consumption).
• Low viscosity in the neat state and fire risk.
• No obnoxious solvent vapor during use.
