Kerry Siam Seaport, a critical logistics hub in Thailand, required long-term protection for its marine structures against harsh environmental conditions. The challenge was to find a coating solution that could withstand constant exposure to saltwater, humidity, and varying temperatures. To address these challenges, the Denso Seashield system was selected for its superior corrosion prevention and sealing technology. The Seashield system provided comprehensive protection to the steel and concrete structures at the seaport, ensuring longevity and reducing maintenance costs. The application of Denso Seashield resulted in enhanced durability of the marine structures, safeguarding Kerry Siam Seaport’s operations from corrosion-related disruptions. This project showcased the effectiveness of Denso Seashield in providing long-term protection in highly corrosive environments.
