Description
Sikaflex NP 1 — Medium Bronze is the current Sika name for the sealant historically sold as MasterSeal / MSeal NP 1. It is a one-component, gun-grade elastomeric polyurethane sealant for moving construction joints and perimeter sealing in concrete, masonry, windows, roofing, siding and other building-envelope applications.
Current Sika data lists ±35% joint movement capability and ASTM C920 Type S, Grade NS, Class 35 performance. The product typically bonds to many common construction materials without primer; follow Sika's current primer requirements for immersion, green concrete and other special conditions.
Legacy/current note: Doug Ashy's ERP row carries the former BASF/MasterSeal product match. The current manufacturer is Sika and the current name is Sikaflex NP 1.
