Structural Adhesives for Metal Bonding,
Magnet Bonding, and Motor
Assembly |
|
Acrylic and methacrylic acid-free, activator-curing structural adhesives brought about the technology revolution, known as "cold bonding", to the magnet and motor assembly industries. These structural adhesives are ideal for choke and transformer bonding, DC motor assembly, alternator, and flywheel applications, tacking, unitizing, ruggedizing, sealing, and shallow potting. This revolutionary resin chemistry has drastically shortened assembly times and saved space, labor, and regulatory compliance costs to make automation easier for manufacturers.
DYMAX 600 and 800 series structural adhesives fixture in seconds, are non-corrosive, non-flammable, and suitable for harsh environments. Additionally, some products cure upon exposure to UV/Visible light or heat. Automated systems are available to conveniently apply adhesives and activators to substrates. The 600 and 800 series structural adhesives for magnet and motor assembly develop strength to 500 psi in seconds, with ultimate bond strengths to 3,500 psi, between opaque surfaces with activator.
