DS-5 100% Solids Epoxy Coating utilizes a unique, multi-component curing system that contributes to a number of superior properties: toughness, permanent flexibility, and improved chemical and temperature resistance. This system may be applied at thicknesses up to 125 mils in single or multiple applications, thereby reducing application costs. The absence of solvent reduces shrinkage, cracking, and disbonding and eliminates problems related to solvent entrapment. MAINSTAY DS-5 is designed for use in corrosive environments with a pH of 0.5 or lower and is typically used as a topcoat over MAINSTAY ML-72 Sprayable Micro silica Restoration Mortar (see section on Application). MAINSTAY DS-5 is particularly well suited for protecting sanitary sewer structures such as manholes, lift stations, wet wells, and sewage treatment plant structures.
