- Knitted or Non-Woven Nylon Carrier
- Lap-Shear, Peel, and Environmental Performance
Product Description
LOCTITE EA 9628 AERO is a modified epoxy film adhesive for structural bonds requiring toughness. It is supplied ready to use with either a knitted nylon carrier as LOCTITE EA 9628K AERO or a non-woven nylon mat as LOCTITE EA 9628NW AERO. The adhesive uses a 235–250°F (113–121°C) heat-cure process and develops temperature-dependent lap shear and peel performance on prepared aluminum. Environmental-exposure testing includes water, humidity, hydraulic oil, JP-4 jet fuel, salt spray, and anti-icing fluid under the documented conditions.
Key features
- Toughened structural film: Modified epoxy construction supports structural bonding applications requiring toughness and durability.
- Two carrier options: Available with knitted nylon or non-woven nylon reinforcement to support different film constructions and cure schedules.
- Elevated-temperature cure: Cures for 1 hour at 250°F (121°C) or 90 minutes at 235°F (113°C).
Applications / Suitable for
- Structural bonded assemblies requiring toughness
- Bonding prepared aluminum adherends
- Metal-to-metal bonded structures
- Aluminum honeycomb sandwich constructions
