A 2-part epoxy coating which once cured forms a barrier coating for the protection of equipment operating under immersed conditions or in contact with aqueous solutions. This solvent free epoxy coating bonds strongly to steel and other metallic and non-metallic surfaces such as concrete or brick.
Belzona 5831 (ST-Barrier) is specifically formulated for application to wet and oil contaminated surfaces that cannot be dry for application, as well as for underwater applications. The coating displaces water from the surface ensuring maximum adhesion to damp or wet surfaces, even underwater.
