Soudal 128450 B2 Gun Grade Fire Expanding Foam 750ml (Pack of 12 )

Description:

Soudal 128450 B2 Gun Grade Fire Expanding Foam is a professional-grade, one-component, polyurethane foam filler with fire-retardant properties. Designed for use with foam applicator guns, this moisture-curing foam provides rapid expansion, excellent adhesion, and superior thermal and acoustic insulation. Classified B2 under DIN 4102, it offers up to 2 hours of fire resistance depending on joint configuration (EN 1366-4). Ideal for passive fire protection and general construction applications, including sealing joints, pipe penetrations, and window or door frame installations.

Features:

  • Fire-rated expanding foam (B2 classification)
  • Up to 2-hour fire resistance (EN 1366-4)
  • High yield per can and box
  • Excellent thermal and acoustic insulation
  • Suitable for use in passive fire protection systems
  • Fast skinning and curing times
  • High adhesion to most construction surfaces (excluding PE, PP, PTFE)
  • No significant shrinkage or post-expansion
  • For gun application only - not hand held
  • Not UV-resistant - must be covered once cured
