Foster® 32-14™ 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.

Foster® 32-17™ Safetee™ Duct Sealant is a fire resistive, fibrated water-based, indoor/outdoor vapor barrier sealant for low, medium and high velocity heating and air-conditioning ducts. It performs as a tough and flexible adhesive and sealant, forming a durable seal against air leakage when used with or without reinforcing tape or membrane. Mechanical fasteners of the type and number normally used for duct assemblies are required to provide rigidity to the duct system.

Foster® 32-19™ Duct-Fas™ Duct Sealant is a fire resistive, water-based, indoor/outdoor, U.V. resistant, non-fibrated sealant for use on low, medium and high velocity ducts to form an extremely flexible, yet durable seal against air leakage. It is supplied in a special thixotropic consistency that allows easy application by brush, glove, trowel, power extrusion or caulking gun.

Foster® 10-42™ Pumpable Cold Sealer is a non-skinning, high solids, non-setting, seam and joint sealant for metal air ducts. It remains soft and flexible, preventing damage to the seal due to thermal cycling through a wide range of temperatures. It has good pumpability, yet quickly achieves excellent blow out resistance. It is designed for use with sheet metal fabrication machines that form locking joints.
