    Product Description

    Dow Froth Pak 620 Spray Foam (Tanks Only.  Gun hose assembly is sold separately) - 341171/347036

    FROTH-PAK Foam Insulation is a closed cell, two-component, quick-cure polyurethane spray foam that fills cavities, penetrations, cracks and expansion joints. Unlike one-component foam, FROTH-PAK Foam Insulation is a chemically cured foam, significantly reducing curing time. It dispenses, expands and becomes tackfree in seconds. The product will skin over in 30–40 seconds and will cure in minutes.*

    Theoretical Yield (Board Feet)= 620 (1.46 m3)

    Kit Includes:

    • 1 Iso (A) cylinder - 341171
    • 1 Polyol (B) cylinder - 347036


    FROTH-PAK™ Foam Sealant can be used in interior or exterior commercial, residential, agricultural, industrial and institutional settings.** If used in an exterior setting, a coating must be applied for ultraviolet (UV) protection.

    Typical commercial applications include spray polyurethane foam roof repair and sealing roof perimeters and parapet walls.

    Residential uses include:

    • Roof and wall junctions
    • Wall and attic penetrations
    • E lectrical, mechanical and plumbing penetrations
    • Other gaps, cracks or crevices in the building envelope


    FROTH-PAK™ Foam Sealant is typically sold as a complete kit that includes pressurized “A” and “B” cylinders, plus dispensing gun/ hose assembly and accessories. FROTH-PAK™ Foam Sealant is also available in refillable, returnable tanks for applications requiring a large amount of foam, such as poultry houses. See Table 1 for size and yield information.

    Physical Properties

    FROTH-PAK™ Foam Sealant exhibits the typical properties and characteristics indicated in Table 2 when tested as represented.

    Fire Information

    FROTH-PAK™ foam is combustible and will burn if exposed to open flame or sparks from highenergy sources. Do not expose to temperatures above 240°F (116°C).


    Complete operating instructions are provided with each FROTH-PAK™ Foam Sealant purchase. Read all information and cautions before application. Note: Avoid overfilling restricted spaces. Chemicals exert force during reaction, and expansion of foam may result in substrate deformation.

    * Actual cure time will depend on temperature, foam thickness, the specific nozzle used, etc.

    ** For rim/band joist applications, use FROTH-PAK™ Foam Insulation (available in U.S. only) to meet building code specifications
