Boat/Marine grade unsaturated polyester resin (UPR) is specially formulated for applications in boat construction and repair. It offers exceptional resistance to water, salt, and humidity, crucial for durability in marine environments. This resin adheres well to fiberglass and provides high mechanical strength, impact resistance, and dimensional stability. Marine grade UPR also prevents osmotic blistering and cures quickly, facilitating efficient manufacturing and repair processes for boat hulls, decks, and structural components. Its reliability makes it a preferred choice among boat builders and repair professionals seeking robust materials for marine applications
