Dottie HF340 Handi-Foam Expanding Sealant

Keep enclosures, conduits and cable penetrations weather-tight and energy-efficient with Dottie Handi-Foam expanding sealant. This 12 oz moisture-cure polyurethane foam sealant is designed for contractors and security integrators who need a fast, reliable way to seal, insulate and sound-dampen around electrical, plumbing and HVAC penetrations. Handi-Foam expands to fill irregular gaps and delivers an R-5 insulation value per inch, reducing heat loss and preventing moisture intrusion that can compromise surveillance, monitoring and networking equipment. The easy bead application is ideal for sealing around camera mounts, junction boxes and low-voltage cable runs without messy cleanup. RoHS-compliant and manufactured in the U.S., Dottie Handi-Foam bonds to common substrates when surfaces are clean and dry, improving indoor air quality and building envelope performance. For secure, long-lasting seals that protect critical systems and boost energy efficiency, apply Dottie Handi-Foam HF340 around conduit, cable trays and camera penetrations — order now or add to your next job kit.
