Structalit ® 5859 is a new adhesive system developed by Panacol specifically for magnet bonding. This adhesive can be used for magnet/rotor bonding and for joining magnets in pole housings.

Structalit ® 5859 is a one-component epoxy resin adhesive that 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 it with material pairings that have different coefficients of thermal expansion. Good gap bridging − to compensate for production-related tolerances −, resistance to aggressive contact media such as oil or coolant and excellent damping properties round off the diverse property profile of this new product.
