Corrosion Protection: Wax Spraying Protocol

Marine environments expose metallic surfaces to chloride-laden aerosols and high humidity, accelerating electrochemical corrosion. To mitigate degradation during ocean transit, wax-based anti-corrosion spraying is strongly recommended.

Application Specifications:

• Product Type: Solvent-based, hydrophobic synthetic wax (e.g., DINITROL 4490, Henkel Aquence)
• Coating Thickness: 20–30 µm
• Coverage Areas: Undercarriage, boom/pivot joints, hydraulic cylinder rods, track links, radiator fins
• Application Method: Electrostatic spray + brush touch-up in crevices
• Curing Time: 4–6 hours (ambient 25°C, 50% RH)
• Protection Duration: Up to 6 months in marine conditions

Benefits:

• Forms a moisture-displacing barrier
• Resists saltwater penetration
• Reduces maintenance costs post-delivery
• Complies with ISO 9223 (corrosivity categories C4–C5)

Note: Wax coating must be applied immediately prior to loading and documented in the pre-shipment inspection report.

---

Recommendations

Shipping Method	Recommended Use Case
RO-RO	Best for high-volume shipments to RO-RO-equipped ports; optimal balance of speed and cost. Requires wax protection due to deck exposure.
Bulk Cargo	Only recommended for cost-sensitive, inland final destinations with bulk-handling infrastructure. High corrosion and damage risk; not advised without full encapsulation.
Flat Rack	Preferred for high-value or precision equipment; enables full access for securing and coating. Ideal when combined with shrink-wrapping and desiccants.

---

Conclusion

For the export of the Yanmar 35 excavator from China, Flat Rack shipping with wax-based anti-corrosion treatment provides the highest integrity solution, particularly for long-haul or high-humidity routes. RO-RO remains a competitive option for established trade lanes with proper protective protocols. Bulk Cargo is discouraged unless logistical constraints necessitate its use.

All shipments should include documented corrosion protection procedures to ensure equipment readiness upon arrival and reduce field downtime for construction fleets.
