3M Fire Barrier CP 25WB+ Sealant in Saudi Arabia
3M Firestop CP 25WB+ :
High-Performance Fire Barrier Sealant
Applications of 3M CP 25WB+
- The 3M™ Fire Barrier CP 25WB+ Sealant is a premium-grade, elastomeric latex-based firestop caulk engineered to provide robust protection against the spread of fire, smoke, moisture, and noxious gases.
-
- This high-performance sealant features advanced intumescent properties, meaning it dynamically expands when exposed to intense heat.
- As combustible items like cable insulation are consumed by fire, the sealant expands to fill the void, maintaining a tight, uncompromising penetration seal.
-
- Formulated for easy application and longevity, CP 25WB+ is a halogen-free, thixotropic caulk that delivers superior adhesion without sagging, making it ideal for both vertical and overhead installations.
-
- Ready to use with standard architectural tools, it provides up to a 4-hour fire resistance rating to help protect property and safeguard lives.
Key Features of 3M CP 25WB+
High Fire Resistance Rating
Achieves up to a 4-hour fire rating to meet stringent commercial building codes.
Advanced Intumescent Property
Expands dynamically under heat to seal gaps left by burned-away cable jacketing and insulation.
Endothermic Thermal Barrier
Actively absorbs heat energy and releases chemically bound water to cool surrounding surfaces.
Thixotropic (No-Sag) Formula
High-viscosity paste that will not sag, drip, or run, ensuring clean overhead and vertical applications.
Water-Based & Easy Clean-Up
Requires no special handling or complex cleanup; excess material washes away easily with water and allows for routine disposal.
Fast-Drying & Paintable
Becomes tack-free in approximately 10 to 15 minutes and can be painted over after a full 72-hour cure.
High Caulk Rate
Engineered for rapid application with a high flow rate of 1000 g/min using a 6mm (1/4") nozzle.
Eco-Conscious Formula
Halogen-free composition with minimal shrinkage and a distinct reddish-brown color for quick inspection and verification.
Integrated Water Seal
Provides immediate waterproof protection against spills and moisture, even in normal conditions.
