One-component, permanently elastic fire-resistant silicone sealant with a neutral curing system for construction seals in ventilation and air-conditioning engineering, as well as for the protection of linear joints (expansion joints) in the field of fire protection. Characterised by fire resistance in the event of a fire, it prevents the spread of fire, smoke and toxic gases through fire barrier joints.

Key benefits:

• recommended for sealing joints in ventilation, smoke ducts and air conditioning;
• tested in accordance with PN-EN 1366-4 (fire resistance tests for service installations - linear joint seals);
• as a stand-alone sealant for joints up to 30 mm wide and up to 40 mm wide when used with the Bostik FP 404 PU foam;
• fire resistance: up to 4 hours;
• permissible deformation capacity: ±25%;
• convenient application and processing;
• highly resistant to run-off and weather;
• high vapour-tightness;
• for indoor and outdoor use.
