MasterSeal NP 1 (formerly known as Sonolastic NP 1) is a one-component, high-performance, non-priming, gun-grade, elastomeric polyurethane sealant. It requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry. Used as an acoustic sealant, MasterSeal NP 1 reduces sound transmission in partition systems to support high STC values by sealing spaces around cut-outs and at perimeters of partitions

  • One-component formula requires no mixing, helping to reduce labor costs
  • Joint movement capability ±35% provides excellent flexibility for keeping moving joints weathertight
  • Easy to gun and tool, speeding up application and making neater joints
  • No primer required for most construction materials lowering installation costs
  • Weather resistant for long-lasting weather tight seals
