MasterSeal Sealant White 10 oz (Model NP1)

MasterSeal NP1 sealant is a one-component, high-performance, non-priming, gun-grade, elastomeric polyurethane. It requires no mixing and typically needs no priming to bond many materials, including concrete and masonry. Used as an acoustical sealant, it lowers sound transmission in partition systems to support high STC values by sealing spaces around cut-outs and at perimeters of partitions. The sealant cures to a tough rubber to form a long-lasting acoustical seal.
