FOSTER HIGH VELOCITY DUCT SEALANT
FOSTER HIGH VELOCITY DUCT SEALANT is a fast setting, elastomeric compound designed as a joint sealant for high velocity air conditioning ducts installed indoors. It may be used with or without reinforcing tapes. It has a mild "paint type" odor and applies cleanly without stringing. Mechanical fasteners of the type and number normally used for duct assemblies are required to provide rigidity to the duct system.
HIGH VELOCITY DUCT SEALANT that can be used to adhere duct fabrics and flexible tubing runouts to high velocity ducts and to mixing boxes or air diffuser heads.
HIGH VELOCITY DUCT SEALANT meets NFPA 90A & 90B 25/50 requirements.
HIGH VELOCITY DUCT SEALANT is produced under the classification and follow- up service of Underwriter's Laboratories, Inc.
HIGH VELOCITY DUCT SEALANT will meet all SMACNA pressure classes up to 10" w.g. and SMACNA seal classes A, B, and C on ducts constructed to SMACNA standards.
HIGH VELOCITY DUCT SEALANT meets requirements for LEED IEQ 4.1 Low-Emitting Materials, Adhesives and Sealants. Sealant Other per SMACNA TRB #9-09. VOC: 408 g/l, less water and exempt solvents.
HIGH VELOCITY DUCT SEALANT contains no asbestos, lead, mercury, or mercury compounds.
Store and apply between 40ºF (4ºC) and 100ºF (38ºC). Always test plastic materials for compatibility when using a solvent base product. Systems may be pressure-tested 36 hours after application, above 60ºF (16ºC). Make certain this product is completely dry and the area free from solvent odor is food is involved. For outdoor application select SAFETEE Duct Sealant 32-17, 32-19, or top-coat 32-14 with a UV resistant finish.
