It is a water-based acrylic emulsion containing graphite, designed to restore fire resistance and insulation performance in compartment walls and floors penetrated by building services. The sealant expands under heat to seal voids left by combustible materials, preventing the passage of flames, smoke, and hot gases during fire conditions.\u003c\/p\u003e\u003cp\u003eFormulated for both combustible and non-combustible services, this sealant provides a reliable, high-expansion barrier for pipes, cables, and insulated metalwork. It reacts at approximately 135°C, rapidly increasing in volume to close openings and restore fire integrity.\u003c\/p\u003e\u003cdiv style=\"margin-top:30px;\"\u003e\n\u003ch2 style=\"font-size:22px;font-weight:700;color:#1a1a2e;margin-bottom:16px;\"\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #e0e0e0;border-radius:4px;overflow:hidden;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#1a1a2e;\"\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eSales Unit\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eBox Quantity\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003e25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures \u0026amp; Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh expansion performance:\u003c\/strong\u003e Graphite-based formula expands at 135°C to close gaps and seal penetrations under fire exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile use:\u003c\/strong\u003e Effective around combustible pipes, single cables, cable bundles, and metal pipes with combustible insulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem compatibility:\u003c\/strong\u003e Suitable for use in both wall and floor applications across multiple substrates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEase of application:\u003c\/strong\u003e Ready-to-use, supplied in 310ml cartridges for standard applicator guns.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire reinstatement:\u003c\/strong\u003e Restores the integrity and insulation performance of compartment walls and floors penetrated by services.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial compatibility:\u003c\/strong\u003e Fully compatible with cPVC pipes and a wide range of building materials.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCombustible pipes:\u003c\/strong\u003e Expands to close voids around plastic and composite service penetrations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCables and cable bunches:\u003c\/strong\u003e Provides a flexible fire seal around grouped electrical services.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal pipes with combustible insulation:\u003c\/strong\u003e Seals annular spaces to maintain compartment integrity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-service penetrations:\u003c\/strong\u003e Suitable for use in mixed penetrations containing various pipe and cable types.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Guidance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreparation:\u003c\/strong\u003e Ensure all surfaces are clean, dry, and free from oil, dust, or loose particles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Apply using a standard mastic or sealant gun, ensuring full contact with surrounding materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth control:\u003c\/strong\u003e For larger gaps, use appropriate backing material before sealing to maintain correct joint depth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinishing:\u003c\/strong\u003e Smooth surface with a wet spatula or gloved finger within 10 minutes of application.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCuring:\u003c\/strong\u003e Allow sufficient time for the sealant to cure fully for optimal performance.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516346909057,"sku":"MM_LB233","price":21.12,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/fb53434e78b18476707c48a8bc238fcc.png?v=1775833204","url":"https:\/\/londonbricks-uk.co.uk\/products\/high-expansion-intumescent-sealant-310ml","provider":"London Bricks UK","version":"1.0","type":"link"}
