PERMABOND® TA440 is a two component structural acrylic adhesive suitable for bonding metals, glass, wood, ferrites, ceramics and some rigid plastics. This adhesive may be used in a variety of structural bonding applications due to its versatile performance capabilities.
Permabond TA440 provides high strength while maintaining excellent flexibility, resulting in tough, durable bonds with outstanding impact and peel resistance. Handling strength is achieved in a few minutes at room temperature.
FEATURES:
- Adhesion to a wide variety of substrates
- Fast cure at room temperature
- No mix application
- High shear and peel strength
- Good impact strength
- Good chemical resistance
APPLICATIONS:
- Aircraft parts (TA4246 is aerospace approved)
- Automotive exterior components• Lifts, stairlifts, stairs and walkways
- Sign bonding, point of sale and shopfitting
- Bus, train, tram interiors
- Vehicle conversions, campervans
- Magnet/ferrite bonding electric motors
- Loudspeaker component bonding
