One and two component epoxy adhesives, sealants and potting compounds offer toughness, high strength adhesion and cost effective performance in electrical motor and generator assembly applications. These compounds are designed to provide thermal stability, resistance to moisture, chemicals, vibration, impact and thermal cycling. Additionally, specific formulations provide superior electrical insulation properties, thermal conductivity and gap filling abilities.
Key Benefits of Master Bond Epoxy System
Adhesive bonding has replaced mechanical fastening tapes, soldering, welding in electrical motor and generator manufacturing and feature the following advantages:
- Weight reduction
- Stresses evenly distributed
- Improved fatigue resistance
- High bond strength to similar and dissimilar substrates
- Prevent corrosion
- Lower costs
- Easily automated
- Enhanced aesthetics
A wide range of systems are available with different cure speeds at ambient and elevated temperatures.
Typical uses include assembly and maintenance, such as:
- Bonding stack laminations
- Encapsulate stators
- Reinforcing wires
- Ring magnets to rotor bonding
- Lead wire tacking
- Armature balancing
Diverse Chemistries Satisfy Multiple Electric Motor and Generator Requirements
Non-corrosive liquid one and two component silicone form-in-place, cure-in-place gasketing compounds feature superior elasticity and high temperature resistance. These versatile systems eliminate the use of cut/molded gaskets, o-rings, minimizing sealant consumption, lower inventory/labor costs, prevent misaligned gaskets, enable effective sealing of different flange configurations while extending life expectancy. Low exothermic epoxy systems have been developed for large volume potting. UV acrylic cure compositions offer fast processing speeds for shallow potting and wire tacking applications. Single component cyanoacrylate adhesives adhere well to metal, rubber, plastic substrates, have clear bond lines and fast fixturing speeds. They are used to reinforce fragile components.
