Belzona® 1321 (Ceramic S-Metal)



Cast Iron substrate, Steel flanges and Bronze bush

Belzona Facts:

Conventional repair by welding and machining to suitable sizes would be very expensive and time consuming. This repair involving bonding different metal sustrates with Belzona eliminates galvanic corrosion and is proven to be fast and safe, saving money by reducing docking time.
