Description
Sikaflex� 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 acoustical sealant Sikaflex� NP 1 reduces 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.
