Belzona (Harrogate, U.K.) reports that, for more than 16 years, its Belzona SuperWrap II composite wrap system has been applied throughout multiple industries to restore the strength of holed, weakened and corroded assets. The company has further optimized this technology’s capabilities with the Belzona 1984 epoxy resin for aqueous environment applications.
“The Belzona SuperWrap II-compliant system already features three resins designed for different application and service temperatures,” explains Ian Wade, technical services manager at Belzona Ltd. “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.”
According to Wade, once cured, the epoxy resin resists temperatures of up to 50°C and can be applied in temperatures ranging from 5-40°C. The Belzona SuperWrap II system can be applied as a composite wrap, pad, plate or patch, depending on application requirements.

The Belzona 1984 system has undergone rigorous testing and is fully approved for compliance with ISO 24817 and ASME PCC-2 standards. These tests used samples which were applied and cured underwater in artificial seawater, representing worst-case and highly aggressive environments.
In order to apply Belzona SuperWrap II to ISO/ASME standards, applicators are required to complete a rigorous training program at one of Belzona’s 16 training centers located worldwide. To uphold this standard, every 2 years, the company’s Corporate Belzona SuperWrap II Trainer Committee conduct a mandatory audit of all Belzona SuperWrap II trainers, facilities as well as internal staff.
