NP 1 is a one-component, high performance, nonpriming, gun-grade, elastomeric polyurethane sealant. It requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry. MDI recommends NP1 because it has proven to be so tough after it has been applied. It is about the only product that will adhere to the airform fabric over time. It is an excellent sealant/bonding agent. * 10.1 fl oz cartridge * 1 year shelf life <b>Related Links:<b> * "Installing an ERV in My Home":http://static.monolithic.com/edcircle/erv/index.html <b>Related Products<b> * "Building Supplies":http://shop.monolithic.com/collections/building-supplies/ * "Airform Products":http://shop.monolithic.com/pages/airform-products <font size="0">007|07 ud</font> <p><span class="caps">NP 1</span> is a one-component, high performance, nonpriming, gun-grade, elastomeric polyurethane sealant.
