750ml Polyurethane Foam Sealant Door And Window Gap Filling Roof Waterproofing Sealant

Characteristics

Polyurethane foam sealant is a versatile, single-component or two-component adhesive-sealant that excels in both bonding and sealing applications across residential, commercial, and industrial settings. It cures upon contact with moisture in the air, expanding to fill gaps, cracks, and irregular spaces—ranging from window and door installations to HVAC duct sealing—creating a tight, seamless barrier. Its key advantages include strong adhesion to a wide range of substrates like wood, metal, concrete, and plastic, excellent thermal insulation to reduce energy loss, and good resistance to water, weathering, and moderate mechanical stress; additionally, it remains flexible after curing, accommodating slight substrate movement without cracking, making it durable for long-term use.

Features

Moisture-Curing Mechanism: Requires only ambient moisture to cure, eliminating the need for special tools or additional catalysts, and allows for easy on-site application.
Expansive Property: Can expand 2–8 times its original volume (depending on the type), ensuring full filling of even large or uneven gaps for comprehensive sealing.
Dual Functionality: Combines strong bonding strength with effective sealing performance, reducing the need for separate adhesives and sealants in one application.
Durable Performance: Offers resistance to UV rays, temperature fluctuations (typically from -40°C to 80°C), and common chemicals, maintaining performance in harsh environments.

Applications

Construction & Renovation: Used for sealing gaps around windows, doors, and siding; bonding insulation boards to walls/roofs; and filling cracks in concrete floors or masonry.
Automotive & Transportation: Applied in vehicle body assembly to seal joints, attach trim components, and insulate engine bays or passenger cabins against noise and heat.
Industrial Manufacturing: Utilized in HVAC systems to seal duct connections, in electrical enclosures to protect components from dust and moisture, and in furniture production to bond frame parts.
Household Repairs: Ideal for fixing loose tiles, sealing gaps around pipes or vents, and reinforcing small structural joints in cabinets, shelves, or outdoor furniture.
