BASF MasterSeal NP1 and NP2 Sealants

NP1 and NP2 are the industries most popular high-performance vertical grade sealants for exterior applications. SL1 and SL2 are the self-leveling versions for expansion joints on grade (horizontal joints). These are high performance moisture-curing polyurethanes. NP1 and NP1 are designed for sealing / caulking all types of active exterior construction joints.

NP1 caulk sealant requires no mixing and bonds to most construction materials without a primer, including concrete, masonry, wood and most metals. NP-2 is a color tintable 3-part sealant which accommodates up to 2" joints with +/- 50% joint movement. NP2 is available in 22 standard colors and up to 470 custom color choices.

Is BASF MasterSeal NP1 the same as BASF Sonneborn NP1?

During late 2014 BASF changed branding from Sonolastic Sonneborn NP1 to Master Builders MasterSeal NP1. It is the same product.
