Marine RTV Firestop Foam

This two-component RTV silicone foam features excellent crack-and-void filling capabilities and provides high resilience to accommodate vibration. MRF is designed as a seal for both deck and bulkhead pipe penetrations, which when properly mixed, expands 2 to 4 times its original volume, filling available spaces and forming an effective barrier against fire, smoke, hot gas and water penetration.
