Foster® 10-42™ 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.

Pumpable Cold Sealer's fiber free and grit free formulation will not clog pumps, hoses, or nozzles.
