The Dow Froth Pak 620 - 2 Spray Sealant Kit has 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 tack-free in seconds. The product will skin over in 30-40 seconds and will cure in minutes.
Theoretical Field: 620 Board Feet, 1.46 m3
Froth Pak 620 spray foam requirements are calculated in "Board Feet". A Board Foot is simply an area of cured foam measuring 12" x 12" x 1" thickness after curing. Example: if you have a surface that is 40' x 8' and want the foam 2" thick you would need 640 board feet (40x8x2 = 640). Confused how much spray foam you need? Give us a call: (888) 405-6064.

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