HB Fuller Fiber Resin EY3211 - Epoxy Adhesive 

HB Fuller Fiber Resin EY3211 is a two-component epoxy adhesive system specifically formulated for demanding aerospace applications. This high-performance adhesive offers exceptional strength, durability, and resistance to environmental factors. 

EY-3211 A/B is a two-component epoxy novolac system. This system does not contain any solvents or diluents; therefore, shrinkage due to flashing off of these solvents is not a consideration. EY-3211 A/B demonstrates good chemical, electrical and physical properties.

Key Features and Benefits:

• High Strength Bond: Provides a strong, durable bond between a variety of substrates, including metals, composites, and plastics.
  
• Excellent Chemical Resistance: Resists a wide range of chemicals, fuels, and solvents.
  
• Temperature Resistance: Maintains bond strength over a wide temperature range.
  
• Low Outgassing: Minimal volatile organic compound (VOC) emissions.
  Fast Cure Time: Achieves high strength in a relatively short time.

Applications:

• Bonding Composite Structures: Used to bond composite panels, honeycomb cores, and other composite structures.
  
• Repairing Damaged Components: Used to repair damaged composite components, such as wings, fuselage, and control surfaces.
  
• Sealing Joints: Used to seal joints and seams in aircraft structures.
  
• Adhering Non-Structural Components: Used to bond non-structural components, such as interior panels and insulation.

Mix Ratio
Mix 2 parts by weight of EY-3211B with 100 parts by weight of EY- 3211A RESIN.
The work life of EY-3211 A/B at 25°C is >4 hours. The gel time for 102 grams is 20-25 minutes @ 125°C

Cure Cycle
The typical cure for motor winding is to impregnate the winding and pull a vacuum at 26Hg minimum to allow excess material to drain. Cure in a circulating air oven for 1 hour @ 150°C.
