The Red Devil 0909 Foam and Fill is a professional-grade triple expanding polyurethane sealant engineered for high-volume gap filling in residential and commercial HVACR applications. This 12 oz aerosol insulating foam sealant is designed to expand up to three times its original liquid volume, effectively sealing deep voids around conduits, wall penetrations, and structural foundations. It creates a robust airtight and waterproof bond that prevents energy loss while acting as a barrier against moisture infiltration, pests, and drafts. For field applications, the expanding polyurethane foam offers a 10-minute tack-free time and reaches a full cure within 24 hours depending on ambient humidity. With an approximate thermal conductivity of 0.22 to 0.25 Btu-in/hr-ft²-°F, it significantly improves the thermal envelope of the building. The polyurethane spray foam is compatible with unpainted wood, concrete, aluminum, and masonry, and once fully cured, it can be sanded, painted, or stained to match the surrounding substrate. This gap and crack filler is formulated without HCFCs or CFCs, ensuring it meets environmental standards without sacrificing adhesion or durability. Key Benefits High expansion ratio fills large voids and irregular cavities with minimal product waste. Superior insulating foam properties with an R-value of approximately 4 to 5 per inch. Creates a waterproof sealant barrier that prevents mold-conducive moisture transport. Maintains structural integrity across a wide temperature range once cured. Straw-applicator nozzle allows for precise delivery in tight mechanical spaces. Common Questions Is Red Devil 0909 UV resistant? Standard polyurethane foams will degrade when exposed to direct sunlight. For exterior applications, the cured foam must be protected with a premium paint or elastomeric coating. What is the ideal application temperature? For optimal expansion and cell structure, apply when ambient temperatures are between 65°F and 100°F. Low-temperature applications may result in slower extrusion and significantly longer cure cycles. Can this be used as a fire-stop? No, this product is designed for thermal insulation and air sealing. It is not rated for use as a fire-stop material in rated assemblies. This item is not eligible for free shipping.
