International supplier of industrial adhesives Panacol has launched a modified, one-component epoxy resin adhesive, called Structalit 5858, developed specifically for bonding magnets into electric motors. The company says its high bond strength and impact resistance ensures reliable bonding.
The new epoxy can be cured thermally in a conventional oven at temperatures from 100°C. It is also possible to use induction curing for faster polymerization and shorter curing cycles. The adhesive requires storage between 0–10°C, but its stable viscosity and reactivity allow it to be processed on the line at ambient temperature for up to seven days.
The adhesive was developed by Panacol to expand its line of adhesives for electric motor assembly. After proper curing, the product generates excellent adhesion to metals. With bond strength over 34 MPa on steel and aluminum, this adhesive creates reliable and high-strength bonds. Even at temperatures above 100°C, it continues to exhibit excellent superior bond strength, ensuring consistent performance during thermal stress. The high impact strength of this modified epoxy ensures that bonded components will not loosen or separate from operational vibration or external forces. Structalit 5858 is particularly suitable for bonding magnets, such as the connection of half-shell magnets in stators, or permanent magnets on rotors.
