Application
Started from military applications, FASTBLOCK®️ by TA Aerospace offers fire protection coatings, sealants and adhesives designed for aircraft structures, propulsion engines, APU’s, ducts, actuators, and wherever the fire zone is on an aircraft. Applications include thermal blanket insulation, heat shields, firewall air, vapor and fluid barriers. FASTBLOCK®️ is used for production, construction, maintenance and repair on manufacturing, commercial, military, rotor, space and custom molded applications.
Commercial Aviation
FASTBLOCK®️ provides thermal insulation and fire protection solutions for the world’s leading commercial aircraft platforms, including the Boeing 737 MAX, Airbus A220, and Airbus A320 families. Commercial operators also rely on FASTBLOCK®️ for rotorcraft applications, including the Bell 525 helicopter platform. Our products deliver critical firewall protection for engines, propulsion systems, ducts, and actuators, meeting stringent FAA AC 20-135 requirements (2000°F for 15 minutes).
Commercial operators rely on FASTBLOCK®️ for maintenance and repair applications where lightweight, high-performance thermal blankets and heat shields are essential. Our sealant, adhesive, and coating formulations provide fluid resistance and vapor barriers that protect critical aircraft structures throughout the service life of the aircraft. Whether applied during manufacturing or as part of AOG (Aircraft on Ground) maintenance, FASTBLOCK®️ products reduce weight while delivering exceptional thermal and fire barrier performance.
Business Jet
Business aviation demands the highest standards of safety and performance. FASTBLOCK®️ serves leading business jet manufacturers and operators, including Gulfstream, Bombardier, Dassault Falcon, and platforms across the Spirit Aerosystems portfolio. Our sprayable, moldable, and paintable formulations provide design flexibility for complex business jet configurations.
From construction to production applications, FASTBLOCK®️ offers tailored solutions for firewall insulation, engine compartment protection, and duct sealing. Business jet operators benefit from our low-VOC, water-based formulas that simplify application while meeting stringent aerospace specifications. FASTBLOCK®️ products are engineered to protect high-value assets with minimal weight penalty, critical for business aviation performance requirements.
Military Applications
FASTBLOCK®️ has a proven heritage in military and defense aviation, protecting critical systems on platforms including Boeing C-130 and C-17 transports, Lockheed Martin F-22 and F-35 fighters, Northrop Grumman aircraft, and emerging defense systems from Collins Aerospace.
Defense applications demand materials that withstand extreme environments while meeting strict military specifications. FASTBLOCK®️ products provide fire protection for engines, propulsion, and structures exposed to temperatures from -148°F to 600°F operational exposure, with fire resistance up to 2000°F for 15 minutes.
From sealant and adhesive applications to thermal blanket insulation, heat shields, and coating systems, FASTBLOCK®️ supports the full lifecycle of military aircraft—from initial production and construction through field maintenance and repair. Our moldable and sprayable solutions enable rapid application in depot maintenance environments, while our fluid resistance and vapor barrier properties protect against hydraulic fluids, lubricants, and jet fuels.
Military aviation also benefits from FASTBLOCK®️’s formulation adaptability. Whether protecting complex actuator assemblies, sealing critical ducts, or providing firewall barriers in tight spaces, TA Aerospace can tailor FASTBLOCK®️ products to meet unique mission requirements.
