It is formulated for both indoor and outdoor applications, making it a versatile choice for HVAC installers, sheet metal contractors, and mechanical insulation professionals. This sealant works on all standard duct types including metal duct, glass fiber duct board, flex duct, duct fabric, and flexible tubing runouts. The synthetic latex composition bonds well to these surfaces and creates a durable, airtight seal that helps reduce air leakage in duct systems. Reducing duct leakage improves system efficiency, lowers energy costs, and keeps conditioned air where it belongs. The white color blends cleanly on light-colored duct systems and finished assemblies. Built-in polyester reinforcement gives this sealant exceptional tensile strength compared to unreinforced alternatives, helping it hold up under the mechanical stress and thermal cycling that duct systems experience over time. UV inhibitors are included in the formula to resist breakdown from sunlight exposure, which makes it suitable for rooftop units, outdoor air handlers, and exposed exterior ductwork. The CCWI-181-WHITE carries a UL 181 A-M and B-M listing, confirming it meets performance requirements for use on Class 1 flexible air ducts and air connectors. It also passes ASTM C-731 and D-2202 testing standards. Additional approvals include USDA, EPA, and FDA recognition, as well as LEED compliance under SCAQMD Rule 1168 for low VOC content. The City of Los Angeles has issued approval RR 8427 for this product. Application temperature range runs from 35 degrees Fahrenheit to 110 degrees Fahrenheit, and the service temperature range extends from -20 degrees Fahrenheit to 200 degrees Fahrenheit once cured. Coverage reaches up to 320 linear feet at 3 inches width and 20-mil thickness per gallon. Dry time is 48 hours under normal conditions. Shelf life is 1 year unopened when stored properly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUL 181 A-M and B-M Listed for use on metal duct, flex duct, duct board, and flexible tubing runouts\u003c\/li\u003e\n\u003cli\u003eBuilt-in polyester reinforcement with UV inhibitors for long-term indoor and outdoor durability\u003c\/li\u003e\n\u003cli\u003eLEED compliant, SCAQMD Rule 1168 approved, low VOC water based formula\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Carlisle CCWI-181-WHITE delivers a code-compliant, reinforced duct seal rated for both indoor and outdoor exposure.
