2. Corrosion Protection: Wax Spraying Protocol

Seawater exposure during ocean transit presents a significant risk of surface and undercarriage corrosion, particularly in tropical and high-humidity maritime zones. SEA LION International mandates a wax-based anti-corrosion treatment for all Groundhog Excavators prior to shipment.

Wax Spraying Specifications

Parameter	Requirement
Wax Type	Solvent-based, hydrophobic synthetic wax
Application Method	High-pressure spray (15–20 bar)
Coverage Areas	Undercarriage, boom joints, track links, hydraulic cylinders, chassis weld zones
Film Thickness	25–35 µm (measured via DFT gauge)
Drying Time	2 hours at 25°C, 60% RH
Removal Process	Biodegradable citrus-based degreaser post-delivery
Protection Duration	Up to 60 days exposure to salt spray (ASTM B117)

This treatment forms a non-conductive, water-repellent barrier that inhibits chloride ion penetration. Field data from 2025 shipments indicate a 76% reduction in post-transit corrosion claims when wax treatment is applied.
