Adhesives continue to play a strong role in the fastening and joining of aerospace components for fabrication, assembly, and repair. Huntsman recently introduced three REACH-compliant epoxy adhesives.

Araldite® EP 1000 A/B epoxy adhesive is a nano-toughened structural adhesive paste with high lap shear strength and good peel strength at temperatures up to 250º F (121º C.)  The translucent epoxy can withstand exposure to aviation fuels and hydraulic fluids.  Suited for bonding composites, metals and dissimilar materials, the durable adhesive can be cured at room- or elevated-temperatures.  And it is easy to extrude from pre-measured, dual barrel cartridges.

Araldite® AW 4859/Hardener HW 4859 epoxy adhesive is formulated for bonding composite aircraft structures including stringers, ribs, spars and flight control surfaces.  The epoxy produces joints with hot/wet strength, a service temperature up to 284º F (140º C), and good moisture and chemical resistance.  Supplied in dual-barrel cartridges and bulk containers, the toughened black adhesive is sag resistant and gap filling.

Araldite® 1570 FST A/B epoxy adhesive is a flame retardant, halogen-free, black paste for bonding and repairing cargo panels as well as other composite and thermoplastic components used in aircraft interiors.  The system meets flame, smoke and toxicity standards, including FAR 25.853 (a) and (a-1) and AITM 3.0005 and is qualified to an Airbus specification.  Lap shear strength of the room-temperature cure material is more than 2,400 psi.
