Panacol Launches Epoxy Adhesive for High-Strength Magnet Bonding

Panacol launches Structalit® 5859, a new adhesive system developed specifically for magnet bonding. The adhesive can be used for magnet/rotor bonding as well as 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 just five minutes. The product has an impressively long open time and can be processed for seven days at room temperature.

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 150°C.

In addition, the adhesive has high impact strength and good elongation at break, which enables it to be used with material combinations with different thermal expansion coefficients. Good gap bridging to compensate for production-related tolerances, resistance to aggressive contact media such as oils or coolants and excellent damping properties round off the versatile performance of this new product.
