Antifouling Coating · Paint & Coating Systems
Marine vessels often require robust protection against corrosion and environmental damage, especially in areas exposed to saltwater and harsh weather conditions. The Jotachar JF750 XT / Fiberfrax Durablanket S - H-60 deck is designed to provide effective hull and tank protection coating systems. This system includes Jotamastic 90 Epoxy Mastic Primer with a dry film thickness (DFT) of 100 µm, Marathon IQ2 solvent-free epoxy topcoat with a maximum DFT of 500 µm, and Penguard Primer with a typical DFT of 60–120 µm. The SeaQuantum Ultra coating has a low VOC content conforming to IMO AFS/CONF/26 standards, ensuring minimal environmental impact. Adhesion requirements are ≥5 MPa, as per ASTM D3359 Level 0–1, and salt spray resistance (ASTM B117) is typically over 1000 hours. Common failure points include insufficient coating thickness, inadequate adhesion, incomplete curing, improper surface preparation, holiday/pinhole defects, and non-conformity with PSPC/IMO standards. Regular inspections and maintenance, including touch-up work and anode checks, are essential to maintain the integrity of the coating system.
