20 OZ BLACK NP1 SIKAFLEX

Description

ONE-COMPONENT, ACOUSTIC/SOUND DAMPING, ELASTOMERIC, GUN-GRADE POLYURETHANE SEALANT

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.
