Flamemaster CS 3213 Class B Corrosion Inhibitive Sealant - High-Performance Sealant with Corrosion Protection for Aircraft

NSN 8030-01-184-0330    

CS 3213 Class B aerospace sealant was designed for sealing metal components on aircraft systems for protection against corrosion. It acts as a barrier between dissimilar metals as well as protecting aluminum alloys against corrosion and is typically used for sealing faying surfaces and sealing joints. 

Key Features for Aviation:

• High-performance sealant specifically designed for aircraft applications with integrated corrosion inhibition.
  
• Provides excellent adhesion to common aircraft substrates like aluminum and composites.
  
• Offers good flexibility to accommodate movement and vibration in aircraft structures.
  
• Actively inhibits corrosion, protecting metal surfaces from degradation.
  
• Resistant to many common aircraft fluids and environmental conditions (always verify specific resistance).
  
• Class B designation indicates specific handling and application characteristics.
  
• Suitable for sealing faying surfaces, joints, and other areas prone to corrosion in aircraft.
  

Typical Aviation Applications:

• Sealing faying surfaces in airframe structures to prevent intergranular corrosion.
  
• Sealing around fasteners and rivets to inhibit corrosion.
  
• Sealing joints and seams where moisture ingress could lead to corrosion.
  
• Protecting dissimilar metal interfaces from galvanic corrosion.
  
• Use in the manufacturing and maintenance of commercial, military, and general aviation aircraft, particularly in environments with high corrosion risk.
