Belzona 1121

Belzona 1121


Belzona 1121 is a cold-curing 100% solids epoxy composite reinforced with silicon steel alloy. It is ideal for applications in hot climates or large areas, where extended working life is required.

These materials can be used for various applications including bonding, shimming, forming, rebuilding, wrapping, patching, sealing and filling.

They will not shrink while curing in service, allowing for exact dimensions and geometry to be achieved. Belzona 1121 ensures lasting in-service performance, accounting for temperature and pressure fluctuations, loading and stresses, impact and abrasion.
Five-year shelf life makes Belzona 1121 an invaluable stock item for many maintenance proffessionals.

Usage areas: Shafts, engine blocks, Casings, pipes, keyways, tanks, flange surfaces, propeller, rudder, bow thruster.
