US-based adhesives and coatings manufacturer Panacol has introduced Structalit 5859, a new adhesive system developed for magnet bonding.

Structalit 5859 is a one-component epoxy resin adhesive that can be used for magnet/rotor bonding and for joining magnets in pole housings. It 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 a long open time and can be processed at room temperature for seven days.

Owing 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. 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 gap bridging to compensate for production-related tolerances, as well as resistance to aggressive contact media such as oil or coolant, and damping properties.
