Rust Preventative Oil P40

RLT-P40 Volatile Film Rust Preventative Oil

Many precision hardware manufacturers face two common troubles during finished product packaging: residual water stains on machined parts trigger early rust, and thick anti-rust film requires extra degreasing steps before assembly, raising production labor costs. ROLITOM designed RLT-P40 volatile film rust preventative oil to solve these two core workshop pain points, a solvent-based anti-corrosion agent optimized for finished metal component packaging and short-to-medium term storage protection.

This rust preventative oil carries excellent water displacement capacity and mild low-odor formula. After application, the solvent inside volatilizes naturally at room temperature, leaving an ultra-thin uniform oily barrier covering all metal surfaces. This thin oil layer effectively blocks salt mist, moisture and airborne corrosive pollutants, delivering stable indoor anti-rust protection up to 18 months for treated workpieces.

Unique Advantages of RLT-P40 Volatile Anti-Rust Oil

Powerful Water Displacement Eliminates Hidden Rust Sources

Residual water film left after workpiece cleaning is the top cause of premature oxidation. RLT-P40 can quickly replace surface water on metal parts, fully removing hidden moisture before forming protective oil film, drastically lowering the risk of rust spots during sealed packaging and storage.

Mild Odor & Safe High Flash Point Formula

Compared with traditional low-flash volatile rust preventatives, RLT-P40 features an open cup flash point over 78℃, greatly reducing fire risks during spraying and dipping operations in closed workshops. Its mild odor creates a more comfortable working environment for frontline operators without harsh solvent fumes.

Ultra-Thin Residual Oily Film, Skip Degreasing Before Assembly

Only a light oily film remains after solvent volatilization. End users can directly assemble unpacked workpieces without extra degreasing, saving dedicated cleaning procedures and cutting auxiliary chemical consumption for downstream factories.

Balanced Long-Term Corrosion Resistance Against Humidity & Salt Fog

Lab test data verifies steady anti-rust performance under harsh test environments: 24 hours salt spray resistance on 45# steel sheets and 120 hours continuous damp heat protection, fully meeting the anti-corrosion demands of indoor storage and short-term outdoor transit.

Wide Application Coverage

RLT-P40 volatile rust preventative oil fits anti-corrosion treatment for all kinds of machined mechanical components, and serves as ideal packaging rust protection for finished metal hardware products. It supports both indoor long-term sealed storage and temporary outdoor turnover protection for workpieces.

Simple On-Site Operation Guidance

• Complete surface cleaning and full dehydration of all metal parts before oil treatment, no residual water or dirt allowed on surfaces.

• Apply RLT-P40 at normal ambient temperature via three available operation methods: full immersion, manual brushing or uniform spraying.

• After solvent volatilization, finished workpieces can be directly packed for storage or shipment. No degreasing step is required before subsequent assembly processing.

• For ultra-precision small parts, seal containers completely after oil application to prevent dust from adhering to the thin oily protective film and affecting surface finish.

Operation & Storage Safety Reminders

• All construction work must be carried out under normal room temperature; strictly stay away from open fire, welding sparks and high-temperature heat sources to avoid fire risks.

• Tightly seal the product storage tank or barrel when idle, to prevent external dust, water and impurities from contaminating the liquid and weakening its water displacement and anti-rust performance.

• Thoroughly remove all moisture, oil residue and metal debris from workpiece surfaces before contact with RLT-P40; incomplete cleaning will greatly shorten the effective anti-rust cycle.

FAQ

Q1: How long is the maximum indoor anti-rust lifespan after one-time application?

A: When workpieces are fully cleaned, properly coated and sealed indoors, the effective anti-rust period can reach up to 18 months. Protection time will be shortened under open-air or high-humidity storage environments.

Q2: Do I need to clean the oil film before assembling the metal parts?

A: No additional degreasing or cleaning is needed. The thin oily residual film will not interfere with assembly fit, and components can be assembled directly after unpacking.

Q3: Which operation ways can I use this volatile rust preventative oil?

A: Three flexible application methods are supported: immersion dipping, manual brushing and spray coating, suitable for small precision parts and large mechanical components respectively.

Q4: Is pre-trial testing required before bulk order purchase?

A: We strongly recommend small batch trial coating before mass procurement. Final anti-rust performance is affected by workpiece material, surface cleaning standard, operation mode and storage humidity. Free sample testing service is available upon request.
