LOCTITE® AA 3342
Known as LOCTITE 3342
Features and Benefits
slide 1 of 1
A 1-part, medium-high viscosity, fast-fixture acrylic adhesive for surface permanent magnet (SPM) bonding in electric motors.
LOCTITE® AA 3342 is a yellow-opaque, modified acrylic-based structural adhesive that provides a 3 to 3.5-minute fixture time, a shear strength of 15–30 N/mm² and very fast curing on activated surfaces. This makes it highly suitable for automated assembly lines with short cycle times. It’s typically used for bonding small rigid parts of dissimilar materials. It tolerates operating temperatures up to 180°C (356°F), making it particularly useful when high heat resistance is required, e.g., when bonding ferrites into motor cans. LOCTITE AA 3342 is a 1-part adhesive but requires activator LOCTITE® SF 7649 before use.
- LOCTITE SF 7649 activator required for use
- Temperature-resistant up to 180°C (356°F)
- Good resistance to impact and humidity
- Dual cure: activator or heat
- Fast fixture time within minutes (3–3.5 min)
