Mainstay DS-5-S Medium Build 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. Mainstay DS-5-S may be applied at thicknesses up to 50 mils in a single or multiple applications, thereby reducing application costs. The absence of solvent reduces shrinkage, cracking, and disbonding and eliminates the problems related to solvent entrapment. Mainstay DS-5-S is particularly well suited for use as a topcoat over Mainstay ML-72 Sprayable Microsilica Restoration Mortar.
