Handi-Foam Extreme Gun Sealant - 24oz

Overview

Handi-Foam Extreme Gun Sealant – 24oz (P30120) is designed for sealing small cracks and voids to prevent air and moisture infiltration in extreme temperature and low humidity conditions.

Technical Features

• Extreme low-pressure, one-component formulation: Simplifies application by eliminating the need for a two-part mixing system, reducing setup time on the job site.
• Moisture-cured chemistry: Activates using ambient humidity in the air, allowing the foam to cure without any additional catalysts or equipment.
• Rated for application temperatures as low as 0°F (-18°C): Maintains workability in cold outdoor environments where standard foam sealants typically fail to cure properly.
• Formulated for low humidity conditions: Engineered to cure reliably even when ambient moisture levels are insufficient for standard polyurethane foams.
• UL GREENGUARD Gold certified: Meets stringent chemical emissions standards, contributing to healthier indoor air quality and supporting green building compliance.
• Gun foam dispensing format: Compatible with the Handi-Tool® Dispensing Unit, providing controlled, precise application and reducing product waste.

Applications

• Sealing small cracks and voids in walls, floors, and structural assemblies to block air infiltration.
• Preventing moisture intrusion around penetrations, window and door frames, and utility openings.
• Cold-weather construction and winterization projects where outdoor temperatures drop to or below freezing.
• Job sites or climates with low ambient humidity where standard moisture-cure foams may not perform reliably.
• Interior applications requiring low-emission, GREENGUARD Gold compliant sealing materials.
