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.

Recommended uses: Interior and exterior, above and below grade, immersed in water, expansion joints, panel walls, precast units, aluminum and wood window frames, roofing, fascia, parapets, vinyl siding, store front assemblies
