Dow Froth Pak 650 Class A (E84) Spray Foam Kit
FROTH-PAK Foam Insulation is a 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.
Theoretical Field:650 Board Feet.
FROTH-PAK Foam Insulation dispenses, expands and becomes tack-free in seconds. The product will skin over in 30-40 seconds and will be completely cured in minutes.
The Class-A rating (flame spread of 25 or less) of FROTH-PAK Foam Insulation allows its use in a wide range of interior and exterior industrial, commercial, institutional and residential settings. Check with local codes prior to use. If used in an exterior setting, a coating must be applied for ultraviolet (UV) protection.
