Lining systems
A long-term solution for protecting against corrosion and rehabilitating America's deteriorating infrastructure is Raven Lining System's 405 ultra high-build epoxy. The product's high physical strength allows it to be designed as a structural lining in manholes, pipelines, tanks, and other deteriorated structures. It has a broad range of chemical resistance but specifically protects against the hydrogen sulfide and sulfuric acid.
