Huntsman Advanced Materials (The Woodlands, Texas) has introduced three high-performance REACH-compliant epoxy adhesives for use by aerospace manufacturers and component suppliers for fabrication, assembly and repair.
- Araldite EP 1000 A/B epoxy adhesive is a nano-toughened structural adhesive paste that features very high lap shear strength and good peel strength at temperatures up to 250ºF/121ºC. The translucent epoxy can withstand exposure to aviation fuels and hydraulic fluids. Well 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 excellent hot/wet strength, has a service temperature up to 284ºF/140ºC and good moisture and chemical resistance. Supplied in convenient 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.
