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.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOne-component formula  requires no mixing, helping to reduce labor costs\u003c\/li\u003e\n\u003cli\u003eJoint movement capability ±35% provides excellent flexibility for keeping moving joints weathertight\u003c\/li\u003e\n\u003cli\u003eEasy to gun and tool, speeding up application and making neater joints\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUsage\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInterior and exterior\u003c\/li\u003e\n\u003cli\u003eAbove and below grade\u003c\/li\u003e\n\u003cli\u003eImmersed in water\u003c\/li\u003e\n\u003cli\u003eExpansion joints\u003c\/li\u003e\n\u003cli\u003ePanel walls\u003c\/li\u003e\n\u003cli\u003ePrecast units\u003c\/li\u003e\n\u003cli\u003eAluminum and wood window frames\u003c\/li\u003e\n\u003cli\u003eRoofing\u003c\/li\u003e\n\u003cli\u003eFascia\u003c\/li\u003e\n\u003cli\u003eParapets\u003c\/li\u003e\n\u003cli\u003eVinyl siding\u003c\/li\u003e\n\u003cli\u003eStorefront assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSubstrates\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConcrete\u003c\/li\u003e\n\u003cli\u003eMasonry\u003c\/li\u003e\n\u003cli\u003eAluminum\u003c\/li\u003e\n\u003cli\u003eWood\u003c\/li\u003e\n\u003cli\u003eClay \u0026amp;
