Who makes NP1 caulk?
BASF MasterSeal NP1
BASF MasterSeal NP1 Caulk polyurethane sealant, formerly Sonneborn NP 1, is a one-component, high performance, no-priming, gun-grade, elastomeric polyurethane sealant.
What type of caulk is NP1?
elastomeric polyurethane sealant
MasterSeal NP 1 (formerly known as Sonolastic 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.
Is MasterSeal NP 1 waterproof?
NP1 isn’t merely water-tight, it can be fully submerged in water without losing its grip or seal. While not recommended for applications that will remain permanently submerged, it can resist even the most powerful sources of water.
How long does it take for MasterSeal NP 1 to dry?
Skins overnight and fully cures within a week. Dries smooth and is paintable. Under ideal conditions: Skins over (24 hrs), Functional (3 days), Full Cure (5-7 days).
What is MasterSeal NP 1 used for?
Used as an acoustical sealant, MasterSeal NP 1 reduces sound transmission in partition systems to support high STC values by sealing spaces around cut-outs and at perimeters of partitions.
Is NP1 caulk paintable?
NP-1TM requires no mixing and typically bonds to many materials without a primer, including concrete and masonry. NP1 dries with a smooth finish and is paintable.
Is NP1 a silicone?
It contains silicone additive for greater flexibility and adhesion. Paintable in just 30 minutes with latex or oil-based paints.
How long before NP1 gets wet?
Ideally, if the humidity level is about 50% and the temperature is 75 °F (24 °C), a total cure will take approximately a full week. For immersion with metal structures submerged in water, the curing time will take around 21 days.
Can you use NP1 as an adhesive?
MasterSeal NP 1 is a one-component, high performance, non-priming, gun-grade, elastomeric polyurethane sealant. It is often used as a construction adhesive. It requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry.
What removes NP1?
How to Remove NP-1 Caulk
- Run a putty knife along the right and left seams of the bead of caulk to loosen the caulk from the surface.
- Slide the edge of the putty knife under the bead of loosened caulking material, and lift it up from the surface, sliding and lifting as far along as you can until the seam of caulk breaks.
