3M Fire Barrier Silicone Sealant 2000+

Overview

3M Fire Barrier Silicone Sealant 2000+ is an elastomeric, ready-to-use, single-component, neutral-cure silicone sealant that cures upon exposure to atmospheric humidity, forming a flexible firestop seal for construction joints and through penetrations in fire-rated assemblies. It is firestop tested up to 3 hours in accordance with ASTM E814 (UL 1479) and CAN/ULC S115, and fire resistance tested up to 4 hours for construction joint systems per ASTM E1966 (UL 2079). It offers ±13% compression and extension capability, is re-enterable and repairable, exhibits exceptional adhesion to most common construction materials, acts as an acoustic barrier minimizing noise transfer, and performs from -40°F to 302°F (-40°C to 150°C).
