FASTBLOCK® 100 Off White TA Standard & AMS 3374F Type 5 Spec Ready-to-Use Firewall Sealant - 6 oz Cartridge

FASTBLOCK 100 SERIES compounds are ready-to-use, moisture-curable firewall sealants for high vibration areas. These one-part, non-ablative sealants cure to tough, durable elastomers upon exposure to air. The materials adhere well to metals, composites, paints, and most other common substrates without the use of primers or special surface preparation. FASTBLOCK 100 SERIES sealants have a paste consistency that makes them effective on vertical and overhead surfaces and in the repair of panel holes. The materials can be dispensed from caulking systems or spread by trowel. Upon exposure to fire, the materials form a strong, dense ceramic char with excellent adhesion and fire blocking properties.
