PANACOL: Adhesive System for Magnet Bonding

The magnets of an electric motor are attached with the Structalit® 5859 shown in blue. Image courtesy of Panacol.
Structalit® 5859 is a new adhesive system specifically for magnet bonding. The adhesive can be used for magnet/rotor bonding and for joining magnets in pole housings.
The one-component epoxy resin adhesive cures at temperatures as low as 100 °C. At 150 °C, the curing time can be reduced to as little as five minutes. The product has an impressively long open time and can be processed at room temperature for seven days.
Due to its high glass transition temperature (Tg) of 143 °C, Structalit 5859 has a tensile shear strength of 17 MPas on steel − even at temperatures of 150 °C. In addition, the adhesive is characterized by high impact strength and good elongation at break, which makes it possible to use with material pairings that have different coefficients of thermal expansion. Additional properties of the adhesive include good gap bridging (to compensate for production-related tolerances), resistance to aggressive contact media such as oil or coolant. and excellent damping properties.
