Cargo tank coating renewal involves removing old coatings and applying new protective layers to prevent corrosion and contamination. Tank and cargo systems maintenance ensures structural integrity and safe transportation of liquid cargo. The process includes inspection, surface preparation, and application of specialized coatings for durability.

Size: Varies based on tank dimensions, typically 20,000 to 100,000 liters.

Grade: Epoxy, polyurethane, or zinc silicate coatings, compliant with IMO PSPC standards.

Viscosity: 50-150 cP (depending on coating type and application method).

Buoyancy: Not applicable (coatings are applied to tank interiors).

Material: High-performance polymers, corrosion-resistant alloys, or composite materials.

Thickness: 200-500 microns (dry film thickness).

Cure Time: 4-24 hours (varies with temperature and coating type).

Adhesion Strength: ≥5 MPa (tested per ASTM D4541).

Chemical Resistance: Resistant to hydrocarbons, acids, and alkalis.

Temperature Range: -30°C to +120°C (operational).

Surface Preparation: Sa 2.5 (ISO 8501-1) or equivalent.

Application Method: Spray, roller, or brush (depending on coating).

Certification: IMO MSC.215(82), MARPOL Annex I, and OCIMF standards.
