Sikaflex NP1 with AWF PRO Gloves - Stone 20oz Polyurethane Sealant – Non Sag, Flexible, Elastomeric Acoustic Sealant, Pack of 10

AWF PRO Gloves for Sikaflex NP 1 (Formerly MasterSeal NP 1). 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. Used as an acoustical sealant, 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.

• NP1 (Formerly MasterSeal NP1) is a premium grade, moisture cured polyurethane sealant that has excellent adhesion and bonds to most construction materials without a primer; can be used in green concrete applications
• Resists aging and weathering and is highly flexible with joint movement capability +/- 35%; wide temperature application range makes NP 1 suitable for all climates
• Designed for all types of joints where the sealant joint depth falls between the maximum depth of 1/2" and minimum depth of 1/4"
• Suitable for water immersion with documented performance in wet areas; compatible with non-rigid coatings and is paintable
• Can be used as an acoustical sealant to increase system STC value; minimizes sound transfer and supports high STC ratings
