OPERATIONS & MAINTENANCE
IT’S A WRAP!
Chloe Hirst introduces a new composite wrap system for aqueous environments
Application of composite wrap system in submerged environment F
or over 16 years, the composite wrap system, Belzona SuperWrap II, has been applied throughout
multiple industries to restore the strength of holed, weakened and corroded assets. Now, the R&D Department at Belzona Limited has honed the capabilities of this technology so that, with the new epoxy resin, Belzona 1984, this technology is now optimised to be applied in aqueous environments.
SURFACE-TOLERANT COMPOSITE REPAIR SYSTEM One of the key experts behind the development of the new surface- tolerant composite repair system, Ian Wade, technical services manager, explains that, “The Belzona SuperWrap II compliant system already features three resins designed for different application and service temperatures. Belzona 1984 is the latest development in this system, engineered specifically with surface tolerance in mind. This resin can be applied directly to damp, wet and underwater surfaces without the need for abrasive blasting.” Wade adds: “Once cured, Belzona 1984 resists temperatures of up
18

to 50°C and can be applied in temperatures ranging from 5°C to 40°C. The system can be applied as a composite wrap, pad, plate or patch, depending on the application requirements.”
FULL COMPLIANCE WITH STANDARDS The new system has undergone rigorous testing and is fully approved for compliance with ISO 24817 and
ASME PCC-2 standards. These tests used samples that were applied and cured underwater in artificial seawater, representing the worst-case and most aggressive environments. Compliance with these standards demonstrates how the system is optimised for use in a variety of challenging environments, making it a welcome addition to many a maintenance engineer’s repertoire of repair solutions.
