Antirust Composite Agent RR640

Many lubricant and metal protection fluid manufacturers face consistent formulation hurdles when developing qualified industrial rust protection oils: poor miscibility with paraffin base oil, insufficient salt spray & damp-heat resistance, and unstable film-forming performance for carbon steel and cast iron parts. RLT-RR640 solves these issues as a versatile composite rust preventive additive.

This integrated raw material is formulated with high-efficiency corrosion inhibitors, dense film-forming components and polar co-solvents. When mixed with paraffin base oil or industrial solvent oil at recommended ratios, the finished anti-rust oil maintains crystal clear liquid state without turbidity or sediment. Formulated from this antirust composite agent, finished rust protection oil delivers outstanding long-term damp-heat and salt spray barrier effects, making it the core composite rust preventive additive for all mainstream temporary and long-term industrial anti-rust oil types.

Product Performance Advantages

1. Excellent universal miscibility with mineral base oils

   This composite rust preventive additive, our flagship antirust composite agent, mixes seamlessly with all grades of paraffin base oil and industrial solvent oil. The blended finished anti-rust liquid stays transparent long-term, eliminating clouding and stratification defects that trouble ordinary single-component rust inhibitors.

2. Premium salt spray & damp-heat anti-corrosion barrier

   After standard 15% dilution test per SH/T0081, oil blended with RLT-RR640 antirust composite agent passes 30-hour continuous salt spray testing on 45# steel. It creates a tight hydrophobic protective film on ferrous metal surfaces to block moisture, oxygen and salt ion erosion, ideal for parts stored in coastal or high-humidity warehouses.

3. Multi-scenario anti-rust oil formulation compatibility

   As a multi-purpose composite rust preventive additive, one single antirust composite agent supports four mainstream anti-rust oil formulas: quick-drying rust preventive oil, water-displacement dehydrating anti-rust oil, thin-film temporary rust protection oil, and sealed long-term storage anti-rust oil, cutting raw material procurement SKUs for fluid factories.

4. Wide applicable ferrous metal coverageFinished oil compounded from this antirust composite agent provides reliable temporary and long-term rust shielding for hardware castings, automotive spare parts, steel stampings, bearing steel and all carbon steel workpieces, covering most general metal processing and storage scenarios.

5. Adjustable dosage matching different anti-rust lifespans

   The usable weight dosage of this composite rust preventive additive ranges from 8% to 15%. Formulators can raise or lower the proportion according to target storage cycle and working environment humidity, balancing raw material cost and corrosion protection grade.

6. Stable physical property with safe operation features

   The antirust composite agent features moderate viscosity and high open flash point above 130℃, complying with petroleum product fire prevention standards. No special high-risk protective equipment is required for daily batching operations.

Usage Guidance

1. Recommended Weight Dosage Range

   Add this antirust composite agent (composite rust preventive additive) into base oil at a ratio of 8 wt% ~ 15 wt%. Tune the proportion up for parts stored in high-salt, high-humidity environments requiring extended anti-rust duration.

2. Standard Mixing Operation

   Stir the composite rust preventive additive uniformly at room temperature before blending with paraffin base oil or solvent oil, to guarantee even film-forming and consistent anti-corrosion performance of finished anti-rust oil.

3. Mandatory Pre-Production Compatibility Trial

   Conduct small lab compatibility and salt spray verification tests before full mass formulation, to confirm finished oil’s film thickness and corrosion resistance match your production requirements.

Storage Specifications

1. Store sealed barrels inside cool, dry, well-ventilated warehouses; avoid long-time direct sunlight and high-temperature heat sources.

2. Fully re-seal barrel lids after partial material extraction to block dust, moisture and foreign contaminants from degrading the antirust composite agent’s activity.

3. Valid shelf life for unopened original sealed drums: 12 months counted from production date. Re-test all core performance indicators if materials pass expiry before reusing for batching.

Packaging Specifications

• Standard 200L metal drum, net weight around 190kg per barrel for regular bulk orders

• Custom 1000L IBC tote tank bulk supply available upon customer advance inquiry

FAQ

Q1: What is the recommended dosage of RLT-RR640 composite rust preventive additive (antirust composite agent) for long-term storage anti-rust oil?

A1: The standard addition range is 8 wt% ~ 15 wt%. For sealed long-term storage oil facing high humidity or salt air environments, we suggest adopting 12%–15% dosage to reach stable 30h salt spray performance on carbon steel.

Q2: What metal materials can anti-rust oil mixed with RR640 composite rust preventive additive protect?

A2: Finished oil compounded from the antirust composite agent delivers reliable corrosion resistance for all ferrous substrates: castings, auto spare parts, steel stampings and bearing steel components.

Q3: Is a pre-production compatibility test required before mass batching this antirust composite agent?

A3: Yes, mandatory small lab trials are required. Different base oil brands will change film-forming and salt spray performance of the composite rust preventive additive; pre-tests avoid mass defective anti-rust oil batches.

Q4: What is the shelf life of unopened RLT-RR640 composite rust preventive additive barrels?

A4: Unopened sealed antirust composite agent drums stored under compliant warehouse conditions carry a 12-month shelf life. Expired raw materials must pass full performance re-inspection before being used for formal formulation.
