This polyurethane-based foam expands up to 50 times its original volume, forming a dense, medium-fine cell structure that effectively fills, seals, and insulates cavities and gaps.\u003c\/p\u003e\u003cp\u003eThe formulation cures rapidly, becoming tack-free in around 8 minutes and ready for cutting or plastering within approximately one hour. This ensures an efficient, clean, and controllable application process.\u003c\/p\u003e\u003cp\u003eThis foam offers strong adhesion to a wide range of construction materials, including concrete, brick, plaster, timber, and metal, making it highly versatile across building and installation tasks. Its cured bead provides long-term load-bearing stability after about 12 hours and remains resilient to temperature fluctuations and moisture exposure.\u003c\/p\u003e\u003cp\u003eIt provides thermal conductivity of 0.04 W\/mK and demonstrates excellent sound-deadening properties, improving both energy efficiency and acoustic insulation. Specifically designed for use with gun foam applicators, it delivers accurate dosing and reduced waste during application.\u003c\/p\u003e\u003cp\u003eThe cured foam withstands long-term temperature ranges between -40 °C and +80 °C, with short-term exposure up to +100 °C, ensuring stability and durability under varying environmental conditions. The 750ml can yields approximately 37 litres of expanded foam when fully cured.\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%;\"\u003eSize\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003e750ml\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%;\"\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\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\u003eQuick Setting Time\u003c\/strong\u003e: Cures within approximately one hour, allowing the filled area to be cut, sawn, or plastered shortly after application.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Expansion Rate\u003c\/strong\u003e: Expands up to 50 times its can volume, enabling effective filling of wide or irregular cavities with minimal material use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent Adhesion\u003c\/strong\u003e: Bonds securely to common building materials including wood, metal, brick, stone, and concrete, ensuring reliable structural support.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal and Acoustic Insulation\u003c\/strong\u003e: Provides a thermal conductivity of 0.04 W\/mK and reduces sound transmission through filled voids and joints.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable and Stable\u003c\/strong\u003e: Maintains full load-bearing performance after 12 hours and resists degradation across a broad temperature range from -40 °C to +100 °C (short-term).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControlled Application\u003c\/strong\u003e: Formulated for use with professional gun applicators, allowing precision control, reduced overspray, and cleaner results.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan Size – 750ml\u003c\/strong\u003e: Expands to approximately 37 litres of cured foam, suitable for extensive sealing and insulation work.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGap Filling\u003c\/strong\u003e: Ideal for sealing around pipe penetrations, window frames, door frames, and irregular masonry voids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFramework Fixing\u003c\/strong\u003e: Used to anchor door and window frames.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516400746881,"sku":"MM_LB1319","price":21.04,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/e8c8bc1ac15fce8db81ea728a3b9bfa3.png?v=1775833593","url":"https:\/\/londonbricks-uk.co.uk\/products\/expanding-foam-gun-grade-750ml-high-expansion","provider":"London Bricks UK","version":"1.0","type":"link"}
