Adelphi A978 is used in the construction of motors and transformers to reduces the core and eddy current losses in stator and hence increases the efficiency of the machine, and reduces humming noise and avoid inter-laminar corrosion.
A978 epoxy is used for bonding stack laminations used in following:
1. Stators stampings stack
2. Rotors stamping stack
3. Gyros, servomechanisms, synchros,
4. Transformers and magnetic amplifier
Solvents. Water. Atmospheric conditions. Temperature changes
