Belzona 1221
Belzona 1221
Belzona 1221 is a two component emergency repair composite based on a ceramic steel reinforced polymer system. This fully machinable Belzona product can be used fort he permanent bonding, repairing or rebuilding of metallic components.
Belzona 1221 can be applied without the need for specialist tools, it will bond strongly to almost any rigid surface.
This multipurpose emergenct repair material will not corrode and is resistant to a wide range of chemicals.
Usage Areas: Tank leakings, pipe leakings, holed casings, plastic-metal expansion joints, bearing seats, isolators, ducts, stripped threads.
