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.
Foster Pumpable Cold Sealer has excellent adhesion to a wide variety of non-porous surfaces. It provides an air tight, long lasting seal for metal-to-metal joints and seams. Mechanical fasteners of the type and number normally used for duct assemblies are required to provide rigidity to the duct system.
Operating temperature: -46°C to 93°C.
