Belzona has developed a two-component, polymer, solvent-free system-Belzona 5871 that provides thermal insulation and corrosion protection while improving the safety, efficiency and durability of industrial equipment
Industries and facilities around the world face challenges linked to the maintenance of pipework, tanks, and vessels. Damage and deterioration of pipes, valves and fittings are a widespread problem and occur due to corrosion, erosion, thermal cycling, and chemical attack.
To save energy costs and reduce waste, companies are recognising the importance of insulating their equipment to prevent heat loss and increase efficiency, however, this creates another issue, corrosion under insulation (CUI). CUI is a major issue which occurs on equipment operating in low, ambient, and high-temperature environments.
The role of insulation for heat conservation is crucial, but also shielding personnel from burns when working with hot machinery and equipment is extremely important as metallic surfaces at ≥ 60°C can lead to hot burns when touched.
Belzona 5871 is designed to be applied onto metal pipework, ducting, tank/vessel externals, and other industrial equipment. It is thermally insulating and improves efficiency while also preventing contact burn injuries, condensation, and icing. It can be applied by brush, cartridge, or heated airless plural spray which is ideal for small, complex geometries or rapid application over large areas, offering a fast return to service and high film build with potentially just one layer of product.
Upon application, the product forms lightweight, high-build closed-cell foam. Due to the foaming epoxy technology, Belzona 5871 expands up to three times its applied thickness e.g. one metre applied gives three-metre cured thickness, thus increasing the amount of product on the surface.
Furthermore, Belzona 5871 is a solvent-free corrosion barrier, eliminating the need for any additional primer or top-coats, reducing the number of layers needed compared to conventional coating solutions. Overcoat times are up to 24 hours irrespective of temperature or humidity providing application flexibility. The cure speed and reduced number of layers required, ensure a fast return to service.
