It is specially designed to reinstate fire resistance, acoustic integrity, and air tightness where building services or joints interrupt compartment lines.\u003c\/p\u003e\u003cp\u003eThe intumescent formulation expands under fire conditions to close small gaps and restrict the passage of flames, smoke, and gases. Once cured, it forms a flexible, durable seal capable of accommodating building movement without cracking or loss of adhesion. Tested to provide up to four hours of fire resistance, the sealant also delivers verified acoustic and air leakage performance, making it suitable for both fire protection and sound control applications across multiple substrates.\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;
