119 Intumescent Fireproof Sealant is a high-performance flame retardant caulk designed for industrial and commercial fire protection applications. This water-based sealant expands over 5 times its original volume when exposed to fire, effectively blocking flame and heat transfer through various penetrations.

• Volume expansion exceeding 5 times during fire exposure
• 40+ years of long-lasting performance with nuclear irradiation resistance
• Halogen-free and sulfur-free formulation for safe, environmentally friendly operation
• Watertight and smoke-tight sealing capabilities
• Non-corrosive and non-toxic smoke emission
• Resistant to LOCA conditions and decontamination agents
• Easy application with 7-10 minute skin-over time

• Shafts and coil cabinets
• Cable penetrations and cable bundle gaps
• Steel pipes with insulation and penetration gaps
• Plastic pipework penetrations (≤50mm)
• HVAC duct penetration gaps

Ensure construction surfaces are clean, dry, and free of dust, oil, moisture, and debris using appropriate cleaning tools.

Load sealant into glue gun and apply evenly into gaps or holes. For larger gaps, fill and compact in layers using appropriate tools.

Compact filled sealant to ensure complete gap filling and surface flatness. Clean excess sealant before curing. Allow natural curing and inspect sealing effectiveness.
