B1 FR GUN GRADE FOAM 750ML

ASMACO GOLD UNIVERSAL MULTI FOAM B1 is a high-performance, fire-retardant polyurethane foamdesigned for quick-setting insulation, sealing, and fire protection applications. This single-component PU foamprovides superior fire resistance, high expansion, and excellent adhesion, making it ideal for construction, renovation, and safety-critical installations.

Key features include a high fire rating (240 minutes), 300% triple expansion, and quick-setting properties, allowing it to be cut, sawn, or plastered within an hour. It offers excellent thermal and acoustic insulation, waterproof and mold-proof protection, and adheres to most building materials, excluding polyethylene, Teflon, and oil-contaminated surfaces. Once cured, it dries rigid, can be trimmed, shaped, sanded, and overpainted, ensuring long-lasting structural integrity.

Ideal for filling gaps around pipe entries through fire-rated walls, sealing fire-rated window and door frames, filling deep joints before plastering or sealing, insulating behind cladding on exterior walls, and securing irregular gaps in stone, brick, concrete, and plaster, this foam ensures high-volume, low-movement fire-rated sealing solutions.

Technical specifications include a fire rating of 240 minutes, tack-free time of 15 minutes, cutting time of 40-50 minutes, foam density of 15-22 kg/m³, foam yield of 35-50 liters, and temperature resistance from -40°C to +90°C, making ASMACO GOLD UNIVERSAL MULTI FOAM B1 a trusted solution for fire-rated insulation and sealing applications.
