Belzona 1321

Belzona 1321 is a two-component, high-strength material for the protection of equipment against erosion-corrosion.

Designed to operate under continuous immersion, up to 60°C, this solvent-free sysyem has outstanding chemical resistance and will bond to a wide range of substrates. Belzona 1321 can alse be used as an injection material fort he shimming and bonding of components.

Usage Areas: Propeller, rudder, stern tube outer shell, bow thruster, pump casings, impellers, valves, kort nozzles, coolers and covers, seawater pipework, tanks, seachests.
