Foster® Pumpable Cold Sealer 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 has a fiber free and grit free formulation that will not clog pumps, hoses or nozzles. Pumpable Cold Sealer meets requirements for LEED IEQ 4.1 Low-Emitting Materials, Adhesives and Sealants.

Material Preparation

Do not thin. Apply only to clean, dry, oil-free surfaces. Keep container closed when not in use.

Application

Designed to be applied with power (pressure) operated equipment or with a bulk-filled, hand caulking gun. Apply a small bead in the seam or joint area and squeeze together for tightness. No open time is necessary.

Power Extrusion - Lock Joint Forming Machines

Foster® Pumpable Cold Sealer may be applied using a wide variety of power (pressure) extrusion equipment suitable for use with solvent-based sealants. It has a typical viscosity range of 200,000 - 400,000 cps. Pumps must include a suitable pail or drum ram and follower plate to prevent cavitation and assure complete emptying of the container. For best application, the material temperature should be 60°F or higher.

Clean Up
Use solvent such as mineral spirits (flammable) or chlorinated solvent (non-flammable) for cleaning tools and equipment.

• Store and apply between 40°F and 100°F.
• Allow 48 hours before pressure testing.
• Not suggested for exposed (surface) application.

¹ - Tested as applied in two 1/8” beads spaced 8 in. on center. Applied to 1/4 inch (6.4 mm) inorganic reinforced cement board. The flame spread may vary at different product thicknesses and/or when applied over other surfaces.
