Corrosion Protection: Wax Spraying Treatment

Overview

Saltwater exposure during maritime transit poses a significant risk to hydraulic systems, undercarriage components, and painted surfaces of excavators. SEA LION International recommends industrial-grade wax-based anti-corrosion spraying as a preventive measure prior to shipment.

Application Protocol

Step	Procedure	Specification
1	Surface Preparation	Degrease and dry all external metal surfaces
2	Wax Application	Spray-applied microcrystalline wax (e.g., Cosmoline-type compound)
3	Coverage Areas	Undercarriage, boom/pivot joints, radiator fins, hydraulic lines, track links
4	Film Thickness	50–75 µm uniform coating
5	Drying & Packaging	Air-dry 2 hours; cover sensitive intakes

Benefits

• Forms hydrophobic barrier against salt-laden air and moisture
• Remains stable over 45-day ocean voyages
• Non-toxic, non-damaging to rubber/plastic seals
• Easily removable with industrial solvents or steam cleaning on-site

Compliance: Meets ISO 9227 (salt spray testing) and MIL-PRF-16173E (preservative compounds).

---

Recommendations

Scenario	Recommended Method	Rationale
High-volume export to EU/US ports	RO-RO	Fast turnaround, low handling risk, ideal for driveable equipment
Remote destination (e.g., West Africa)	Bulk Cargo	Wider port access; cost-effective despite higher damage risk
Non-operational or disassembled units	Flat Rack	Accommodates irregular dimensions; secure lashing options
High-corrosion risk routes (tropical)	All methods + Wax Spray	Mandatory corrosion protection regardless of shipping mode

---

Conclusion

For the export of the ‘Blue Excavator’ from China, RO-RO shipping offers the optimal balance of speed, safety, and cost for operational units bound to developed markets. Bulk cargo remains viable for cost-sensitive shipments to ports with limited infrastructure. Flat rack containers provide flexibility for non-standard configurations. Universal application of wax-based anti-corrosion treatment is strongly advised across all methods to mitigate seawater-induced degradation and ensure equipment readiness upon delivery.

SEA LION International supports integrated logistics planning, including pre-shipment preservation, multimodal coordination, and customs documentation for global deployment.
