Abstract:

A two component adhesive composition which is curable by induction heating is provided. The presence of an effective amount of conductive carbon black along with an effective amount of an electromagnetic energy absorbing material such as iron oxide in the adhesive composition allows one to reduce the time for induction curing and/or allow the use of low frequency induction generators (less than or equal to 10 KHz) in the bonding of fiber reinforced engineering thermoset, thermoplastic materials and other plastics.
