501 UW is a solvent free, ceramic reinforced epoxy coating formulated for use in persistently wet or submerged environments. Its advanced composition delivers high mechanical strength, chemical resistance, and flexibility, ideal for demanding conditions where structural movement and moisture are constant factors.
