The Filoform MD+ Sealant is a high-performance, one-component elastomeric sealing mastic specifically engineered to deliver long-lasting gas-tight, water-tight, and fire-resistant protection for cable and pipe penetrations in ducts and boreholes. Designed for demanding industrial applications, this versatile sealing compound bonds effectively to a wide range of substrate materials including PVC, PE, lead, steel, and concrete.
Formulated as an intumescent compound, Filoform MD+ Sealant expands when exposed to extreme heat or direct flame, creating an effective fire stop that prevents the spread of toxic gases, smoke, and fire through duct channels. Additionally, it offers exceptional resistance against aggressive chemical substances, including Hydrocarbon gases, Methane, and Hydrogen Sulphide (H2S), safeguarding electrical and telecommunication infrastructure against hazardous underground environments.
Key Features of Filoform MD+ Sealant
- Intumescent Fire Protection: Expands upon exposure to heat, holding a fire resistance rating of up to 200°C.
- Gas & Water Tight: Resists water pressure and prevents dangerous gas migration inside cable ducting.
- Substrate Compatibility: Strong adhesion to PE, PVC, concrete, aluminum, and lead-sheathed cables.
- Re-enterable & Non-Toxic: Solvent-free, non-hazardous formulation that allows for future cable entry and maintenance.
Installation & Application Guidelines
To achieve a certified seal, ensure duct surfaces are clean and free of debris. Apply the mastic smoothly into the cavity using a standard caulking tool or the Ultraflow Cartridge dispenser. Smooth the surface using a damp Finishing Sponge to ensure full perimeter contact and eliminate air pockets around complex cable bundles.
