Belzona 1983 (SuperWrap II)

Composite Repair System

Composite repair system for restoring the strength of corroded, weakened and holed pipe and tank walls

Belzona SuperWrap II is a composite repair solution designed to restore strength to weakened or holed metallic substrates. Developed for applications on pipes and process vessels, it is also suitable for safety critical and pressurised systems, and can be used on bends, tees and other complex geometries.

A unique combination of a 100% solids resin, carbon and glass fibre reinforcement sheet, and a compression film ensures a quick and simple application. It can remain maintenance-free for up to 20 years.

The system is available in three different resin grades, Belzona 1981, Belzona 1982 and Belzona 1983, making it suitable for applications in various climates and service temperatures ranging up to 150°C/302°F.

Belzona SuperWrap II is available in a choice of three resin grades designed for applications in cooler or hotter climates, as well as for high temperature service of up to 150°C/302°F.
