Magnet Bonding Adhesives

Reliably bond permanent magnets to rotors or stators

Magnets are everywhere and so is magnet bonding. It is an application used in a wide range of industries, including electrical machinery, power tools, the automotive industry, audio and video equipment, household appliances an other fields. The production of e-motors, in particular, is a booming industry in which magnet bonding plays a vital roles – especially when it comes to driving efficiency.

How do magnet adhesives work?

Magnet bonding adhesives work by filling even the tiniest gaps in order to fix the magnet securely in position through a durable, high strength bond.

There are two main bonding designs:

Surface Permanent Magnets (SPM)

Magnets are bonded to the outside surface of a laminated steel rotor that rotates. Therefore, adhesive should be strong enough to resist the centrifugal force.

Internal Permanent Magnets (IPM)

Magnets are bonded inside the rotor or stator. This is usually done by dropping the magnets into existing slots and bonding them.

To meet our customers' manufacturing needs we offer a comprehensive line of LOCTITE® magnet bonding adhesives. Paired with technical expertise and high-quality equipment system solutions we support engineers within their design and production process.

What do LOCTITE® Magnet Bonding Adhesives offer?

LOCTITE® Bonding Solutions are superior vs. Traditional Methods (clips or springs)

Due to uniform stress load and airtight gap closing, they avoid vibration and corrosion - thus extending  the long lifetime of the device. Automation friendliness allows for cost reduction and simplified operation running.

Benefits of LOCTITE® Magnet bonders:

  • Prevents air gaps
  • Avoids vibrations
  • Makes them impact resistant

In comparison: Mechanical methods interfere with the magnetic field and will also put local stress on the magnet (prone to wear and tear). Also, air gaps will lead to vibration and can cause heat pockets to form (efficiency loss).

Dispensing is key to the solution

Over the past 30 years, we have designed, built and integrated advanced equipment solutions for our customers. From water-thin liquids to high-viscosity pastes, LOCTITE equipment is capable of dispensing and curing a wide variety of adhesives, sealants and other industrial fluids like acrylics, anaerobics, cyanoacrylates and epoxies.

With our high-quality equipment system solutions, we offer a complete line, comprehensive testing and global on-site engineering support to assist with consultation, repairs, joint product development, custom designs and more to fit our customers' magnet bonding needs.

LOCTITE® AA 3510 is one of our latest innovations. As a light cure adhesive (main cure) with secondary anaerobic cure, it allows for fast fixture time in shadowed areas.

A truly total solution approach thanks to globally available dispensing equipment.
