Belzona 2141
Belzona 2141
Belzona 2141 is an elastomeric system designed for coating applications subject to the extremely high localised pressures created by cavitation and erosion.
This versatile liquid applied material retains adhesion under long term immersion and dissipates energy created under medium to high intensity cavitation conditions.
Belzona 2141 can ve injected/formed or applied as either a one or two coat system by brush or applicator.
Usage Areas: Shafts, rudder, stern tube outer shell, kort nozzle, bow thruster, valves, pipework.
