Stack Lamination & Motor Assembly

Electric Motor Industry

Our well renowned Electric Motor Product Line offers adhesives that are specifically formulated to withstand the many conditions that electric motors may be exposed to. Our products have been trusted to bond rotor and stator laminations, magnets, cyclotrons, and cosmotrons. We also offer high temperature electrical potting compounds and powdered epoxies for electrical insulating and electric conductivity as well as UV curable adhesives for temporary metal maskants and insulating coatings.

Stack Lamination

• Magna-Tac E645 is our most popular product in the Electric Motor Industry. This epoxy is used for bonding stack laminations used in stators, rotors, gyros, servomechanisms, synchros, transformers, and magnetic amplifiers. It can also be used as an insulting varnish for impregnated coils and small electrical equipment. Bonding is achieved by heat. Only sufficient pressure to assure complete contact is needed. This adhesives is a great choice as an adhesive/dielectric in the fabrication of magnetic accelerator units such as cyclotrons and cosmotrons. This adhesive has been used in motors which meet US Air Force DWG #Z8019406 Rev E
• Magna-Tac F310 is also designed for high temperature applications including motor laminates and transformer cores. This epoxy is formulated with exceptionally low hydrolysable chloride for exception chemical resistance to aggressive solvents and concentrated acids

UV Curable Protective Coatings 

• Magna-Cryl 2464 is a UV curable permanent protective coating conforming to Boeing BMS 1060A for exposure to jet fuels and other aircraft fluids.
• Magna-Cryl 2510 is a UV curable protective insulating coating for cold rolled steel and other metals. This provides excellent electrical insulation.
• Magna-Cryl 2825 is a UV curable protective coating designed to protect metals during the plating process. It offers excellent adhesion for clean and precise masking yet allows for easy removal anytime during of after the plating process without cracking, breaking, or splitting.

Potting Compounds

• Magna-Tac BU120D is a high strength 100% reactive potting compound. Ideal for high performance applications involved the bonding of all metals and other rigid materials such as glass, ceramics, and structural laminates to themselves
• Magna-Tac M773 cures at room temperature to a tough semi-rigid polymer. It has good wetting and adhesives and is free flowing to penetrate voids and gives good air release and a smooth high gloss surface
• Magna-Tac M677 is a UL94 V-) compliant, flame retardant, self-leveling, high strength epoxy. This adhesive is commonly used for encapsulating/potting electronic/electrical devices, bonding skins to cores, bonding rigid expanded plastic foams to themselves or to metal, plywood, or other rigid materials.

Magnet Bonding

• The below epoxies are ideal for magnet bonding based on their strength, gap and void filling.
  • Magna-Tac 620  in a "no-mix" 100% reactive solvent free epoxy. Fully cured bonds exhibit minimal shrinkage, are electrical insulators and provide excellend resistance to weahter, galvanic action and most chemicals acids
  • Magna-Tac 650 is a solvent free, low VOC, thixaptopic two part epoxy perfect for magnet bonding. Can be applied by trowel or automated systems.
