Adhesives and coatings manufacturer Panacol has introduced Structalit 5859, a new adhesive system developed specifically for magnet bonding. This one-component epoxy resin adhesive can be used for magnet/rotor bonding and for joining magnets in pole housings.
Structalit 5859 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 MPa 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. The adhesive also provides good gap bridging to compensate for production-related tolerances, resistance to aggressive contact media such as oil or coolant, and excellent damping properties to round off the diverse property profile of the new product.
