Raven 405 is formulated to provide structural renewal for severely deteriorated wastewater infrastructure. It is a solvent-free 100% solids, ultra-high-build epoxy coating formulated with high physical strengths and broad-range chemical resistance. It exhibits strong bond to concrete, steel, masonry, fiberglass and other surfaces. Designed for operating temperatures up to 200°F, its unique ultra-high-build ability allows it to be spray applied on vertical and overhead surfaces. The surface tolerance and high physical strengths of this product allow it to be designed as a structural lining in manholes, pipelines, tanks and other deteriorated structures.
