A two-component polyurethane foam that will stop running water. Used for sealing risers, conduits, ducts, and abandoned gas pipes against water, gas, and debris. Packed in a patented, portable dispenser that mixes and dispenses two-component materials with the ease of a caulking tube. Q-Pak 2000 – Duct Sealing Foam is the safest duct seal foam because it protects against eruption. It expands 8 times its volume. One-year shelf-life. Use with the Heavy-Duty Injection Gun (79521). The dispenser is a rugged, all plastic, standard-sized caulking cartridge containing a circular motionless mixer. The two components mix internally and therefore, never come in contact with the installer. Q-Pak 2000 – Duct Sealing Foam requires no special procedures and no clean-up of special tools or equipment. The product is installed with a standard 10 oz Caulking Gun (79521) or power application system. Q-Pak 2000 – Duct Sealing Foam is shipped in a kit containing a Q-PAK cartridge, foam packing material, ram rod, and protective gloves. Q-Pak 2000 – Duct Sealing Foam seals virtually any size or type of pipe or conduit, whether PVC, ABS, metal, or fiberglass. The foam can be easily removed to pull out cable or to open a previously sealed conduit for new cable installation. Q-Pak 2000 – Duct Sealing Foam is mixed and dispensed in one step with no measuring, no manual mixing, and no product waste, so the product is always completely mixed in the correct ratio. It expands 8 times its volume. Q-Pak 2000 – Duct Sealing Foam does not contain TDI or MOCA. The water-blown chemistry makes the product safer to use for the installer and the environment. Q-Pak 2000 – Duct Sealing Foam displays excellent adhesion to most surfaces, including all types of conduit and cable sheaths, without the use of primers. It reacts 50% of full strength in approximately 3 minutes and 80% within 60 minutes after mixing. Q-Pak 2000 – Duct Sealing Foam has excellent mechanical and electrical properties. It is a low-exotherm, fast-setting product that is tough; flows and foams around all shapes; and is easily re-enterable.
