Belzona 5831 (ST-Barrier) is an environmental moisture-tolerant barrier coating for the protection of metallic and non-metallic surfaces. It has been specifically formulated for application to surfaces that cannot be dry for application. The product displaces contaminants from the surface ensuring maximum adhesion to damp, wet or oily surfaces and even underwater. This solvent-free material can be applied to virtually any surface and will cure even in lowtemperature environments, as well as underwater.

Belzona 5831 (ST-Barrier) is an epoxy coating that can be applied to wet and oily metal and concrete surfaces to protect them against corrosion.

Belzona 5831 (ST-Barrier) is used to protect a riser in an oil rig against the harsh offshore environment which causes severe corrosion problems. This high technology epoxy coating displaces water and oil from the surface and bonds strongly to almost any metal including stainless steel, carbon steel, aluminium and copper. Thanks to this characteristic, the coating can be applied to wet and even underwater surfaces to protect them against seawater corrosion on offshore structures such as risers and platform legs
