14077 CRC Sealant, FOAM Minimal Expansion Aerosol, 16 oz Aerosol

CRC Minimal Expansion Foam is the simple way to fill, seal, bond, retrofit, insulate and deaden sound in and around cavities. The UL Classified, polyurethane foam forms a permanent, waterproof and airtight bond to masonry, wood, glass, metal and most plastics. It stops drafts, dust, moisture, insects and rodents. Minimal Expansion Foam cures to a semi-rigid, closed cell foam that insulates to R-5 for each inch of foam. It uses a non-flammable propellant and a 360? valve for safe and accurate dispensing. Minimal Expansion Foam is also reusable for up to 30 days after initial use.
