Product Description
LOCTITE EA 9380.05 AERO is a two-part aerospace epoxy paste adhesive for low-temperature cure that can be applied to large parts by controlled meter mix or dual-cartridge static mixer. The system mixes 100:45 by weight. At 25 deg C, working life is 2 to 3 hours in a 0.4 mm layer. It fully cures in 2 hours at 82 deg C, and an alternative cure cycle is 1 hour at 104 deg C. Typical tensile lap shear is 35.0 MPa at 25 deg C on phosphoric-acid-anodized 2024-T3 bare aluminum after a 2-hour cure at 93 deg C. It is used for aerospace structural bonding where toughness and heat resistance are required.
Key features
- Meter-Mix Application: The adhesive can be applied to large parts by controlled meter mix or dual-cartridge static mixer.
- Long Working Window: Working life is 2 to 3 hours at 25 deg C in a 0.4 mm layer.
- Low-Temperature Cure: The adhesive fully cures in 2 hours at 82 deg C.
Applications
Aerospace structural bonding where low-temperature cure, toughness, and high-strength paste-adhesive performance are required.
