To GE and other electric item rebuilders,
If you feel the need to seal your motors or other electric items with
silicone you must use a neutral cure silicone sealer. The stuff you buy at
Home Depot gives off acetic acid as it cures. (You can smell it.) If
off inside of a closed container, like our GE DC motors, it will build up
a high enough concentration where you will get corrosion of exposed metals
(commutators) and/or bearings. I damaged some automotive motors this way
before I knew there was a neutral cure in existance.
You can order neutral cure electronic grade silicone sealer from Newark
Electronics. I am not sure where else it is available, although Radio
might have it as a catalog order item.
I have rebuilt six mower motors and so far not needed to use sealers
anywhere. I'd be interested to know if the need for silicone sealer is
