Carboguard 640 stands as an optimal, high-performance, high-build coating suitable for various applications and structures, be it in marine or industrial settings, necessitating water or corrosion resistance. It boasts a well-documented history of long-term service, particularly in marine hull exteriors both above and below water, as well as in the lining of hydro penstocks, gates, and similar structures permanently immersed in water. Notably, Carboguard 640 is the preferred barrier coating when used in conjunction with Sea~BarrierĀ® 1000 and 3000 antifoulings.
