PERMABOND® TA459 is a structural acrylic adhesive designed primarily for bonding metals, ferrites, ceramics and some thermoplastics. This product was specifically designed to be non-corrosive to sensitive copper parts or other electrically conductive surfaces. The fast curing rate and rapid strength development of this material allows for increased production rate.
Use TA459 with Initiator 41 (or Initiator 43 for use on plastics).
FEATURES:
- Adhesion to a wide variety of substrates
- Fast cure at room temperature
- Excellent adhesion to metals and ferrites
- Acid-free and non-corrosive
- No mix application
- High shear 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
