Single component Polyurethane Foam

Zerodraft foam sealant seals gaps and cracks in walls, roof-wall connections, the perimeter of doors and window openings, mechanical and electrical penetrations and similar locations to provide a continuous, impermeable barrier to air infiltration or loss.


Uses -Zerodraft foam sealant:

• is intended to be installed at junctions to seal between different building elements and around penetrations in a building assembly.
• is dispensed as a bead or crack gap filling. A crack being less than 6mm (1/4 in) wide and a gap being less than 50mm (2in) wide.
• can be trimmed and painted where appearance is an issue.


Limitations:

Do not use Zerodraft foam sealants:
• Where it is subject to continuous service temperatures are outside the range of -60°C to +80°C such as in contact with chimneys, heater vents, steam pipes, etc. unless the sealant has been designed for use and other service temperature as specified by Zero Draft.
• On or in the vicinity of heat emitting devices such as recessed lighting fixtures, at a lesser distance than 75 mm (3 “) or as specified by the authority having jurisdiction.
• Inside electrical outlets or junction boxes.
• Left exposed to continuous ultra violet light.
• Immersed in water for long periods of time.


Features

• High yield; a standard 24 oz can will produce 280 linear meters of 13mm diameter bead.
• Quick cure; tack free in 8 minutes and cut through in 45 minutes (50% relative humidity).
• Fire retardant; self extinguishing in absent of flame produces flame spread rating of less than 25 and smoke develop rating of less than 50 when tested to CAN/ULC-S102 and ASTM E-84 in a range of bead sizes. (not a fire stop; see Zerodraft Air Seal/Fire Stop Systems literature)
• Safe formula; does not contain urea formaldehyde, CFC’s, chlorofluorocarbons or solvents.
• Excellent insulating properties; 70% closed cell content provides RSI value of 0.961 per 305 mm thickness (R Value of 5.4 per 1” thickness).
