Mainstay DS-5 is designed for use where corrosion is anticipated or known to be aggressive. DS-5 is also ideal for secondary containment applications where moderate concentrations of acids (ex: unlimited immersion in 30% sulfuric acid) exist. Mainstay DS-5 is particularly well suited for use as a topcoat over Mainstay ML-72 or Mainstay ML-72F Sprayable Microsilica Mortar.
