3M Fire Barrier Water Tight Sealant 1000 NS (nonslump) and 3M Fire Barrier Water Tight Sealant 1003 SL (self-leveling) are both ready-to-use, one component, silicone elastomers. Both cure upon exposure to atmospheric humidity to form a flexible seal.
3M Fire Barrier Water Tight Sealant 1000 NS and 1003 SL are used to firestop openings and penetrations fire rated floor slabs, walls, other building partitions and assemblies. The 3M Fire Barrier Water Tight Sealant 1003 SL formulation is used in floor applications only. 3M Fire Barrier Water Tight Sealants, when properly installed, will help control the spread of fire, smoke and noxious gases. 3M Fire Barrier Water Tight Sealant 1000 NS and 1003 SL also meet the new UL Water Leakage Test, W Rating – Class 1 requirements for systems tested and listed in accordance with ANSI/UL1479.
